# REST API Documentation

API default service port is `6420`. However, if running the desktop or standalone releases from the website, the port is randomized by default.

A REST API implemented in Go is available,
see [Skycoin REST API Client Godoc](https://godoc.org/github.com/skycoin/skycoin/src/api#Client).

The API has two versions, `/api/v1` and `/api/v2`.

## API Version 1

`/api/v1` endpoints have no standard format. Most of them accept formdata in POST requests,
but a few accept `application/json` instead. Most of them return JSON but one or two
return a plaintext string.

All endpoints will set an appropriate HTTP status code, using `200` for success and codes greater than or equal to `400` for error.

`/api/v1` endpoints guarantee backwards compatibility.

## API Version 2

*Note: API Version 2 is under development, and not stable. The guidelines here are subject to change.*

`/api/v2` endpoints have a standard format.

All `/api/v2` `POST` endpoints accept only `application/json` and return `application/json`.

All `/api/v2` `GET` requires accept data in the query string.
In the future we may have choose to have `GET` requests also accept `POST` with a JSON body,
to support requests with a large query body, such as when requesting data for a large number
of addresses or transactions.

`/api/v2` responses are always JSON. If there is an error, the JSON object will
look like this:

```json
{
    "error": {
        "code": 400,
        "message": "bad arguments",
    }
}
```

Response data will be included in a `"data"` field, which will always be a JSON object (not an array).

Some endpoints may return both `"error"` and `"data"`. This will be noted in the documentation for that endpoint.

All responses will set an appropriate HTTP status code indicating an error, and it will be equal to the value of `response["error"]["code"]`.

Since `/api/v2` is still under development, there are no guarantees for backwards compatibility.
However, any changes to the API will be recorded in the [changelog](../../CHANGELOG.md).

Under some circumstances an error response body may not be valid JSON.
Any client consuming the API should accomodate this and conditionally parse JSON for non-`200` responses.

## API Sets

API endpoints are grouped into "sets" which can be toggled with the command line parameters
`-enable-api-sets`, `-disable-api-sets` and `-enable-all-api-sets`.

These API sets are:

* `READ` - All query-related endpoints, they do not modify the state of the program
* `STATUS` - A subset of `READ`, these endpoints report the application, network or blockchain status
* `TXN` - Enables `/api/v1/injectTransaction` and `/api/v1/resendUnconfirmedTxns` without enabling wallet endpoints
* `WALLET` - These endpoints operate on local wallet files
* `PROMETHEUS` - This is the `/api/v2/metrics` method exposing in Prometheus text format the default metrics for Skycoin node application
* `NET_CTRL` - The `/api/v1/network/connection/disconnect` method, intended for network administration endpoints
* `INSECURE_WALLET_SEED` - This is the `/api/v1/wallet/seed` endpoint, used to decrypt and return the seed from an encrypted wallet. It is only intended for use by the desktop client.
* `STORAGE` - This is the `/api/v2/data` endpoint, used to interact with the key-value storage.

## Authentication

Authentication can be enabled with the `-web-interface-username` and `-web-interface-password` options.
The username and password should be provided in an `Authorization: Basic` header.

Authentication can only be enabled when using HTTPS with `-web-interface-https`, unless `-web-interface-plaintext-auth` is enabled.

## CSRF

All `POST`, `PUT` and `DELETE` requests require a CSRF token, obtained with a `GET /api/v1/csrf` call.
The token must be placed in the `X-CSRF-Token` header. A token is only valid
for 30 seconds and it is expected that the client obtains a new CSRF token
for each request. Requesting a CSRF token invalidates any previous CSRF token.

A request rejected for invalid or expired CSRF will respond with `403 Forbidden - invalid CSRF token`
as the response body.

### Get current csrf token

## Simple query APIs

### Get balance of addresses

API sets: `READ`

```
URI: /api/v1/balance
Method: GET, POST
Args:
    addrs: comma-separated list of addresses. must contain at least one address
```

Returns the cumulative and individual balances of one or more addresses.
The `POST` method can be used if many addresses need to be queried.

Example:

```sh
curl http://127.0.0.1:6420/api/v1/balance?addrs=7cpQ7t3PZZXvjTst8G7Uvs7XH4LeM8fBPD,nu7eSpT6hr5P21uzw7bnbxm83B6ywSjHdq,2jBbGxZRGoQG1mqhPBnXnLTxK6oxsTf8os6
```

Result:

```json

    "confirmed": {
        "coins": 21000000,
        "hours": 142744
    },

            }
        }
    }
}
```

### Get unspent output set of address or hash

API sets: `READ`

```
URI: /api/v1/outputs
Method: GET, POST
Args:
    addrs: address list, joined with ","
    hashes: hash list, joined with ","
```

Addrs and hashes cannot be combined.

In the response, `"head_outputs"` are outputs in the current unspent output set,
`"outgoing_outputs"` are head outputs that are being spent by an unconfirmed transaction,
and `"incoming_outputs"` are outputs that will be created by an unconfirmed transaction.

The current head block header is returned as `"head"`.

The `POST` method can be used if many addresses or hashes need to be queried.

Example:

```sh
curl http://127.0.0.1:6420/api/v1/outputs?addrs=6dkVxyKFbFKg9Vdg6HPg1UANLByYRqkrdY
```

or

```sh
curl http://127.0.0.1:6420/api/v1/outputs?hashes=7669ff7350d2c70a88093431a7b30d3e69dda2319dcb048aa80fa0d19e12ebe0
```

Result:

### Get unconfirmed transactions of a wallet

API sets: `WALLET`

```
URI: /api/v1/wallet/transactions
Method: GET
Args:
    id: Wallet ID
    verbose: [bool] include verbose transaction input data
```

Returns all unconfirmed transactions for all addresses in a given wallet

If verbose, the transaction inputs include the owner address, coins, hours and calculated hours.
The hours are the original hours the output was created with.
The calculated hours are based upon the current system time, and are approximately
equal to the hours the output would have if it become confirmed immediately.

### Generate new address in wallet

API sets: `WALLET`

```
URI: /api/v1/wallet/newAddress
Method: POST
Args:
    id: wallet file name
    num: the number you want to generate
    password: wallet password
```

For `bip44` type wallets, the new addresses will be generated on the `external` chain (`change=0`).

Example:

```sh
curl -X POST http://127.0.0.1:6420/api/v1/wallet/newAddress \
 -H 'Content-Type: x-www-form-urlencoded' \
 -d 'id=2017_05_09_d554.wlt' \
 -d 'num=2' \
 -d 'password=$password'
```

Result:

```json
{
    "addresses": [
        "TDdQmMgbEVTwLe8EAiH2AoRc4SjoEFKrHB"
    ]
}
```

### Scan addresses in wallet

API sets: `WALLET`

This API would scan wallet addresses ahead to search for addresses that currently have unspent outputs (coins) associated with them.

```
URI: /api/v1/wallet/scan
Method: POST
Args:
    id: wallet file name
    num: the number you want to scan ahaed [optional(default to 20), must be > 0 if provided]
    password: wallet password
```

The return value is a list of `new` generated addresses after scanning.

Example:

```sh
curl -X POST http://127.0.0.1:6420/api/v1/wallet/scan \
-F id=test.wlt \
-F num=10 \
-F password="${password}"
```

Result:

```json
{
    "addresses": [
        "TDdQmMgbEVTwLe8EAiH2AoRc4SjoEFKrHB"
    ]
}
```

### Change wallet label

API sets: `WALLET`

```
URI: /api/v1/wallet/update
Method: POST
Args:
    id: wallet file name
    label: wallet label
```

Example:

```sh
curl -X POST http://127.0.0.1:6420/api/v1/wallet/update \
 -H 'Content-Type: application/x-www-form-urlencoded' \
 -d 'id=$id' \

### Create transaction

API sets: `WALLET`

```
URI: /api/v1/wallet/transaction
Method: POST
Content-Type: application/json
Args: JSON body, see examples
```

Creates a transaction, returning the transaction preview and the encoded, serialized transaction.
The `encoded_transaction` can be provided to `POST /api/v1/injectTransaction` to broadcast it to the network
if the transaction is fully signed.

The request body includes:

* An optional change address
* A wallet to spend from with the optional ability to restrict which addresses or which unspent outputs in the wallet to use
* A list of destinations with address and coins specified, as well as optionally specifying hours
* A configuration for how destination hours are distributed, either manual or automatic
* Additional options

`change_address` is optional. If not provided and the wallet is a `deterministic` type
wallet, then the change address will default to an address from one of the
unspent outputs being spent as a transaction input.  If the wallet is a `bip44` type
wallet, then a new, unused change address will be created.

Example request body with manual hours selection type, unencrypted wallet and all wallet addresses may spend:

```json
{
    "hours_selection": {
        "type": "manual"
    },
    "wallet_id": "foo.wlt",
    "change_address": "nu7eSpT6hr5P21uzw7bnbxm83B6ywSjHdq",
    "to": [{
        "address": "fznGedkc87a8SsW94dBowEv6J7zLGAjT17",
        "coins": "1.032",
        "hours": "7"
    }, {
        "address": "7cpQ7t3PZZXvjTst8G7Uvs7XH4LeM8fBPD",
        "coins": "99.2",
        "hours": "0"
    }],
    "unsigned": false,
    "ignore_unconfirmed": false
}
```

Example request body with auto hours selection type, encrypted wallet, specified spending addresses:

```json
{
    "hours_selection": {
        "type": "auto",
        "mode": "share",
        "share_factor": "0.5"
    },
    "wallet_id": "foo.wlt",
    "password": "foobar",
    "addresses": ["2iVtHS5ye99Km5PonsB42No3pQRGEURmxyc"],
    "change_address": "nu7eSpT6hr5P21uzw7bnbxm83B6ywSjHdq",
    "to": [{
        "address": "fznGedkc87a8SsW94dBowEv6J7zLGAjT17",
        "coins": "1.032"
    }, {
        "address": "7cpQ7t3PZZXvjTst8G7Uvs7XH4LeM8fBPD",
        "coins": "99.2"
    }],
    "unsigned": false,
    "ignore_unconfirmed": false
}
```

Example request body with manual hours selection type, unencrypted wallet and spending specific unspent outputs:

```json
{
    "hours_selection": {
        "type": "manual"
    },
    "wallet_id": "foo.wlt",
    "unspents": ["519c069a0593e179f226e87b528f60aea72826ec7f99d51279dd8854889ed7e2", "4e4e41996297511a40e2ef0046bd6b7118a8362c1f4f09a288c5c3ea2f4dfb85"],
    "change_address": "nu7eSpT6hr5P21uzw7bnbxm83B6ywSjHdq",
    "to": [{
        "address": "fznGedkc87a8SsW94dBowEv6J7zLGAjT17",
        "coins": "1.032",
        "hours": "7"
    }, {
        "address": "7cpQ7t3PZZXvjTst8G7Uvs7XH4LeM8fBPD",
        "coins": "99.2",
        "hours": "0"
    }],
    "unsigned": false,
    "ignore_unconfirmed": false
}
```


The `hours_selection` field has two types: `manual` or `auto`.

If `manual`, all destination hours must be specified.

If `auto`, the `mode` field must be set. The only valid value for `mode` is `"share"`.
For the `"share"` mode, `share_factor` must also be set. This must be a decimal value greater than or equal to 0 and less than or equal to 1.
In the auto share mode, the remaining hours after the fee are shared between the destination addresses as a whole,
and the change address. Amongst the destination addresses, the shared hours are distributed proportionally.

When using the `auto` `"share"` `mode`, if there are remaining coin hours as change,
but no coins are available as change from the wallet (which are needed to retain the coin hours as change),
the `share_factor` will switch to `1.0` so that extra coin hours are distributed to the outputs
instead of being burned as an additional fee.
For the `manual` mode, if there are leftover coin hours but no coins to make change with,
the leftover coin hours will be burned in addition to the required fee.

All objects in `to` must be unique; a single transaction cannot create multiple outputs with the same `address`, `coins` and `hours`.

For example, this is a valid value for `to`, if `hours_selection.type` is `"manual"`:

```json
[{
    "address": "fznGedkc87a8SsW94dBowEv6J7zLGAjT17",
    "coins": "1.2",
    "hours": "1"
}, {
    "address": "fznGedkc87a8SsW94dBowEv6J7zLGAjT17",
    "coins": "1.2",
    "hours": "2"
}]
```

But this is an invalid value for `to`, if `hours_selection.type` is `"manual"`:

```json
[{
    "address": "fznGedkc87a8SsW94dBowEv6J7zLGAjT17",
    "coins": "1.2",
    "hours": "1"
}, {
    "address": "fznGedkc87a8SsW94dBowEv6J7zLGAjT17",
    "coins": "1.2",
    "hours": "1"
}]
```

And this is a valid value for `to`, if `hours_selection.type` is `"auto"`:

```json
[{
    "address": "fznGedkc87a8SsW94dBowEv6J7zLGAjT17",
    "coins": "1.2"
}, {
    "address": "fznGedkc87a8SsW94dBowEv6J7zLGAjT17",
    "coins": "1.201"
}]
```

But this is an invalid value for `to`, if `hours_selection.type` is `"auto"`:

```json
[{
    "address": "fznGedkc87a8SsW94dBowEv6J7zLGAjT17",
    "coins": "1.2"
}, {
    "address": "fznGedkc87a8SsW94dBowEv6J7zLGAjT17",
    "coins": "1.2"
}]
```

To control which addresses to spend from, specify `addresses`.
A subset of the unspent outputs associated with these addresses will be chosen for spending,
based upon an internal selection algorithm.

To control which unspent outputs to spend from, specify `unspents`.
A subset of these unspent outputs will be chosen for spending,
based upon an internal selection algorithm.

`addresses` and `unspents` cannot be combined.

If neither `addresses` nor `unspents` are specified,
then all outputs associated with all addresses in the wallet may be chosen from to spend with.

`change_address` is optional.
If set, it is not required to be an address in the wallet.
If not set, it will default to one of the addresses associated with the unspent outputs being spent in the transaction.

`ignore_unconfirmed` is optional and defaults to `false`.
When `false`, the API will return an error if any of the unspent outputs
associated with the wallet addresses or the wallet outputs appear as spent in
a transaction in the unconfirmed transaction pool.
When `true`, the API will ignore unspent outputs that appear as spent in
a transaction in the unconfirmed transaction pool when building the transaction,
but not return an error.

`unsigned` is optional and defaults to `false`.
When `true`, the transaction will not be signed by the wallet.
An unsigned transaction will be returned.
The `"txid"` value of the `"transaction"` object will need to be updated
after signing the transaction.
The unsigned `encoded_transaction` can be sent to `POST /api/v2/wallet/transaction/sign` for signing.

Example:

```sh
curl -X POST http://127.0.0.1:6420/api/v1/wallet/transaction -H 'content-type: application/json' -d '{
    "hours_selection": {
        "type": "auto",

    },
    "wallet_id": "foo.wlt",
    "change_address": "uvcDrKc8rHTjxLrU4mPN56Hyh2tR6RvCvw",
    "to": [{
        "address": "2Huip6Eizrq1uWYqfQEh4ymibLysJmXnWXS",
        "coins": "1"
    }, {
        "address": "2Huip6Eizrq1uWYqfQEh4ymibLysJmXnWXS",
        "coins": "8.99"
    }]

### Sign transaction

API sets: `WALLET`

```
URI: /api/v2/wallet/transaction/sign
Method: POST
Content-Type: application/json
Args: JSON body, see examples
```

Signs an unsigned transaction, returning the transaction with updated signatures and the encoded, serialized transaction.
The transaction must spendable to be signed. If the inputs of the transaction are not in the unspent pool, signing fails.

Specific transaction inputs may be signed by specifying `sign_indexes`, otherwise all transaction inputs will be signed.
`sign_indexes` is an array of positional indexes for the transaction's signature array. Indexes start at 0.

Signing an input that is already signed in the transaction is an error.

The `encoded_transaction` can be provided to `POST /api/v1/injectTransaction` to broadcast it to the network, if the transaction is fully signed.

Example:

```sh
curl -X POST http://127.0.0.1:6420/api/v2/wallet/transaction/sign -H 'content-type: application/json' -d '{

## Key-value storage APIs

Endpoints interact with the key-value storage. Each request require the `type` argument to
be passed.

Currently allowed types:

* `txid`: used for transaction notes
* `client`: used for generic client data, instead of using e.g. LocalStorage in the browser

### Get all storage values

API sets: `STORAGE`

```
Method: GET
URI: /api/v2/data
Args:
    type: storage type
    key [string]: key of the specific value to get
```

If key is passed, only the specific value will be returned from the storage.
Otherwise the whole dataset will be returned.

If the key does not exist, a 404 error is returned.

Example:

```sh
curl http://127.0.0.1:6420/api/v2/data?type=txid
```

Result:

```json
{
    "data": {
        "key1": "value",
        "key2": "{\"key\":\"value\"}",
    }
}
```

Example (key):

```sh
curl http://127.0.0.1:6420/api/v2/data?type=txid&key=key1
```

Result:

```json
{
    "data": "value"
}
```

### Add value to storage

API sets: `STORAGE`

```
Method: POST
URI: /api/v2/data
Args: JSON Body, see examples
```

Sets one or more values by key. Existing values will be overwritten.

Example request body:

```json
{
    "type": "txid",
    "key": "key1",
    "val": "val1"
}
```

Example:

```sh
curl -X POST http://127.0.0.1:6420/api/v2/data -H 'Content-Type: application/json' -d '{
    "type": "txid",
    "key": "key1",
    "val": "val1"
}'
```

Result:

```json
{}
```

### Remove value from storage

API sets: `STORAGE`

```
Method: DELETE
URI: /api/v2/data
Args:
    type: storage type
    key: key of the specific value to get
```

Deletes a value by key. Returns a 404 error if the key does not exist.

Example:

```sh
curl http://127.0.0.1:6420/api/v2/data?type=txid&key=key1
```

Result:

```json
{}
```

## Transaction APIs

### Get unconfirmed transactions

API sets: `READ`

```
URI: /api/v1/pendingTxs
Method: GET
Args:
    verbose [bool] include verbose transaction input data
```

If verbose, the transaction inputs include the owner address, coins, hours and calculated hours.
The hours are the original hours the output was created with.
The calculated hours are calculated based upon the current system time, and provide an approximate
coin hour value of the output if it were to be confirmed at that instant.

Example:

```sh
curl http://127.0.0.1:6420/api/v1/pendingTxs
```

Result:

```json

### Create transaction from unspent outputs or addresses

API sets: `TXN`

```
URI: /api/v2/transaction
Method: POST
Args: JSON Body, see examples
```

Creates an unsigned transaction from a pool of unspent outputs or addresses.
`addresses` and `unspents` cannot be combined, and at least one must have elements in their array.

The transaction will choose unspent outputs from the provided pool to construct a transaction
that satisfies the requested outputs in the `to` field. Not all unspent outputs will necessarily be used
in the transaction.

If `ignore_unconfirmed` is true, the transaction will not use any outputs which are being spent by an unconfirmed transaction.
If `ignore_unconfirmed` is false, the endpoint returns an error if any unspent output is spent by an unconfirmed transaction.

`change_address` is optional. If not provided then the change address will
default to an address from one of the
unspent outputs being spent as a transaction input.

Refer to `POST /api/v1/wallet/transaction` for creating a transaction from a specific wallet.

`POST /api/v2/wallet/transaction/sign` can be used to sign the transaction with a wallet,
but `POST /api/v1/wallet/transaction` can create and sign a transaction with a wallet in one operation instead.
Otherwise, sign the transaction separately from the API.

The transaction must be fully valid and spendable (except for the lack of signatures) or else an error is returned.

Example request body with manual hours selection type, spending from specific addresses, ignoring unconfirmed unspent outputs:

### Get transaction info by id

API sets: `READ`

```
URI: /api/v1/transaction
Method: GET
Args:
    txid: transaction id
    verbose: [bool] include verbose transaction input data
    encoded: [bool] return the transaction as hex-encoded serialized bytes
```

If verbose, the transaction inputs include the owner address, coins, hours and calculated hours.
The hours are the original hours the output was created with.
If the transaction is confirmed, the calculated hours are the hours the transaction had in the block in which it was executed..
If the transaction is unconfirmed, the calculated hours are based upon the current system time, and are approximately
equal to the hours the output would have if it become confirmed immediately.

Example:

```sh
curl http://127.0.0.1:6420/api/v1/transaction?txid=a6446654829a4a844add9f181949d12f8291fdd2c0fcb22200361e90e814e2d3

### Inject raw transaction

API sets: `TXN`, `WALLET`

```
URI: /api/v1/injectTransaction
Method: POST
Content-Type: application/json
Body: {"rawtx": "hex-encoded serialized transaction string"}
Errors:
    400 - Bad input
    500 - Other
    503 - Network unavailable (transaction failed to broadcast)
```

Broadcasts a hex-encoded, serialized transaction to the network.
Transactions are serialized with the `encoder` package.
See [`coin.Transaction.Serialize`](https://godoc.org/github.com/skycoin/skycoin/src/coin#Transaction.Serialize).

If there are no available connections, the API responds with a `503 Service Unavailable` error.

Note that in some circumstances the transaction can fail to broadcast but this endpoint will still return successfully.
This can happen if the node's network has recently become unavailable but its connections have not timed out yet.

The recommended way to handle transaction injections from your system is to inject the transaction then wait
for the transaction to be confirmed. Transactions typically confirm quickly, so if it is not confirmed after some
timeout such as 1 minute, the application can continue to retry the broadcast with `/api/v1/resendUnconfirmedTxns`.
Broadcast only fails without an error if the node's peers disconnect or timeout after the broadcast was initiated,
which is a network problem that may recover, so rebroadcasting with `/api/v1/resendUnconfirmedTxns` will resolve it,
or else the network is unavailable.

`POST /api/v1/transaction` accepts an `ignore_unconfirmed` option to allow transactions to be created without waiting
for unconfirmed transactions to confirm.

Any unconfirmed transactions found in the database at startup are resent. So, if the network broadcast failed but
the transaction was saved to the database, when you restart the client, it will resend.

It is safe to retry the injection after a `503` failure.

To disable the network broadcast, add `"no_broadcast": true` to the JSON request body.
The transaction will be added to the local transaction pool but not be broadcast at the same time.
Note that transactions from the pool are periodically announced, so this transaction will still
be announced eventually if the daemon continues running with connectivity for enough time.

Example:

```sh
curl -X POST http://127.0.0.1:6420/api/v1/injectTransaction -H 'content-type: application/json' -d '{
    "rawtx":"dc0000000008b507528697b11340f5a3fcccbff031c487bad59d26c2bdaea0cd8a0199a1720100000017f36c9d8bce784df96a2d6848f1b7a8f5c890986846b7c53489eb310090b91143c98fd233830055b5959f60030b3ca08d95f22f6b96ba8c20e548d62b342b5e0001000000ec9cf2f6052bab24ec57847c72cfb377c06958a9e04a077d07b6dd5bf23ec106020000000072116096fe2207d857d18565e848b403807cd825c044840300000000330100000000000000575e472f8c5295e8fa644e9bc5e06ec10351c65f40420f000000000066020000000000000"
}'
```

Result:

```json
"3615fc23cc12a5cb9190878a2151d1cf54129ff0cd90e5fc4f4e7debebad6868"
```

Example, without broadcasting the transaction:

```sh
curl -X POST http://127.0.0.1:6420/api/v1/injectTransaction -H 'content-type: application/json' -d '{
    "rawtx":"dc0000000008b507528697b11340f5a3fcccbff031c487bad59d26c2bdaea0cd8a0199a1720100000017f36c9d8bce784df96a2d6848f1b7a8f5c890986846b7c53489eb310090b91143c98fd233830055b5959f60030b3ca08d95f22f6b96ba8c20e548d62b342b5e0001000000ec9cf2f6052bab24ec57847c72cfb377c06958a9e04a077d07b6dd5bf23ec106020000000072116096fe2207d857d18565e848b403807cd825c044840300000000330100000000000000575e472f8c5295e8fa644e9bc5e06ec10351c65f40420f000000000066020000000000000",

### Get transactions for addresses

API sets: `READ`

```
URI: /api/v1/transactions
Method: GET, POST
Args:
    addrs: Comma separated addresses [optional, returns all transactions if no address is provided]
    confirmed: Whether the transactions should be confirmed [optional, must be 0 or 1; if not provided, returns all]
    verbose: [bool] include verbose transaction input data
```

If verbose, the transaction inputs include the owner address, coins, hours and calculated hours.
The hours are the original hours the output was created with.
If the transaction is confirmed, the calculated hours are the hours the transaction had in the block in which it was executed.
If the transaction is unconfirmed, the calculated hours are based upon the current system time, and are approximately
equal to the hours the output would have if it become confirmed immediately.

The `"time"` field at the top level of each object in the response array indicates either the confirmed timestamp of a confirmed
transaction or the last received timestamp of an unconfirmed transaction.

The `POST` method can be used if many addresses need to be queried.

To get confirmed transactions for one or more addresses:

```sh
curl http://127.0.0.1:6420/api/v1/transactions?addrs=7cpQ7t3PZZXvjTst8G7Uvs7XH4LeM8fBPD,6dkVxyKFbFKg9Vdg6HPg1UANLByYRqkrdY&confirmed=1
```

To get unconfirmed transactions for one or more addresses:

```sh
curl http://127.0.0.1:6420/api/v1/transactions?addrs=7cpQ7t3PZZXvjTst8G7Uvs7XH4LeM8fBPD,6dkVxyKFbFKg9Vdg6HPg1UANLByYRqkrdY&confirmed=0
```

To get both confirmed and unconfirmed transactions for one or more addresses:

```sh
curl http://127.0.0.1:6420/api/v1/transactions?addrs=7cpQ7t3PZZXvjTst8G7Uvs7XH4LeM8fBPD,6dkVxyKFbFKg9Vdg6HPg1UANLByYRqkrdY

### Get transactions with pagination

```
URI: /api/v2/transactions
Method: GET
Args:
    addrs: Comma separated addresses [optional, returns all transactions if no address is provided]
    confirmed: Whether the transactions should be confirmed [optional, must be 0 or 1; if not provided, returns all]
    verbose: [bool] include verbose transaction input data
    page: Page number [optional, default to 1, must be greater than 0]
    limit: The transactions number per page [optional, default to 10, maximum to 100]
    sort: Sort the transactions by block seq [optional, default to asc, must be 'asc' or 'desc']
``` 

This API is almost the same as the `v1` version, except that it would not return all transactions by default and has
pagination supported. If there are unconfirmed transactions, they will be appended after the confirmed transactions.

If no argument is provided, the first 10 transactions will be returned. The response would have a `page_info` field which
includes `total pages`, `page size`, and `current page`.

Example:

```sh
curl http://127.0.0.1:6420/api/v2/transaction?page=1024&limit=2
```

### Resend unconfirmed transactions

API sets: `TXN`, `WALLET`

Method: POST
```

Example:

```sh
curl -X POST 'http://127.0.0.1:6420/api/v1/resendUnconfirmedTxns'
```

Result:

```json
{
    "txids":[

    ]
}
```

### Verify encoded transaction

API sets: `READ`

```
URI: /api/v2/transaction/verify
Method: POST
Content-Type: application/json
Args: {"unsigned": false, "encoded_transaction": "<hex encoded serialized transaction>"}
```

If the transaction can be parsed, passes validation and has not been spent, returns `200 OK` with the decoded transaction data,
and the `"confirmed"` field will be `false`.

If the transaction is structurally valid, passes validation but has been spent, returns `422 Unprocessable Entity` with the decoded transaction data,
and the `"confirmed"` field will be `true`. The `"error"` `"message"` will be `"transaction has been spent"`.

`"unsigned"` may be specified in the request. If `true`, the transaction will report an error if it is fully signed.
It will not report an error if the transaction is missing at least one signature, and the remainder of the transaction is valid.
In the response, if the transaction has any unsigned inputs, the `"unsigned"` field will be `true`.
If the request did not specify `"unsigned"` or specified it as `false`, the response will return an error for an unsigned transaction.

If the transaction can be parsed but does not pass validation, returns `422 Unprocessable Entity` with the decoded transaction data.
The `"error"` object will be included in the response with the reason why.
If the transaction's inputs cannot be found in the unspent pool nor in the historical archive of unspents,
the transaction `"inputs"` metadata will be absent and only `"uxid"` will be present.

If the transaction can not be parsed, returns `400 Bad Request` and the `"error"` object will be included in the response with the reason why.

Example of valid transaction that has not been spent:

```sh
curl -X POST -H 'Content-Type: application/json' http://127.0.0.1:6420/api/v2/transaction/verify \

### Get block by hash or seq

API sets: `READ`

```
URI: /api/v1/block
Method: GET
Args:
    hash: get block by hash
    seq: get block by sequence number
    verbose: [bool] return verbose transaction input data
```

If verbose, the transaction inputs include the owner address, coins, hours and calculated hours.
The hours are the original hours the output was created with.
The calculated hours are the hours the transaction had in the block in which it was executed.

Example:

```sh
curl http://127.0.0.1:6420/api/v1/block?hash=6eafd13ab6823223b714246b32c984b56e0043412950faf17defdbb2cbf3fe30

### Get blocks in specific range

API sets: `READ`

```
URI: /api/v1/blocks
Method: GET, POST
Args:
    start: start seq
    end: end seq
    seqs: comma-separated list of block seqs
    verbose: [bool] return verbose transaction input data
```

This endpoint has two modes: range and seqs.
The `seqs` parameter cannot be combined with `start`, `end`.

If `start` and/or `end` are provided, returns blocks in the range [`start`, `end`].
Both start and end sequences are included in the returned array of blocks.

If `seqs` is provided, returns blocks matching the specified sequences.
`seqs` must not contain any duplicate values.
If a block does not exist for any of the given sequence numbers, a `404` error is returned.

If verbose, the transaction inputs include the owner address, coins, hours and calculated hours.
The hours are the original hours the output was created with.
The calculated hours are the hours the transaction had in the block in which it was executed.

Example:

```sh
curl http://127.0.0.1:6420/api/v1/blocks?start=101&end=102
```

Result:

```json

### Get last N blocks

API sets: `READ`

```
URI: /api/v1/last_blocks
Method: GET
Args:
    num: number of most recent blocks to return
    verbose: [bool] return verbose transaction input data
```

## Migrating from the unversioned API

The unversioned API are the API endpoints without an `/api` prefix.
These endpoints are all prefixed with `/api/v1` now.

`-enable-unversioned-api` was added as an option to assist migration to `/api/v1`
but this option was removed in v0.26.0.

To migrate from the unversioned API, add `/api/v1` to all endpoints that you call
that do not have an `/api` prefix already.

For example, `/block` would become `/api/v1/block`.

## Migrating from the JSONRPC API

The JSONRPC-2.0 RPC API was deprecated in v0.25.0 and removed in v0.26.0.

Anyone still using this can follow this guide to migrate to the REST API:

* `get_status` is replaced by `/api/v1/blockchain/metadata` and `/api/v1/health`
* `get_lastblocks` is replaced by `/api/v1/last_blocks`
* `get_blocks` is replaced by `/api/v1/blocks`
* `get_outputs` is replaced by `/api/v1/outputs`
* `inject_transaction` is replaced by `/api/v1/injectTransaction`
* `get_transaction` is replaced by `/api/v1/transaction`

## Migrating from /api/v1/spend

The `POST /api/v1/spend` endpoint is deprecated and will be removed in v0.26.0.

To migrate from it, use [`POST /api/v1/wallet/transaction`](#create-transaction) followed by [`POST /api/v1/injectTransaction`](#inject-raw-transaction).
Do not create another transaction before injecting the created transaction, otherwise you might create two conflicting transactions.

`POST /api/v1/wallet/transaction` has more options for creating the transaction than the `/api/v1/spend` endpoint.
To replicate the same behavior as `/api/v1/spend`, use the following request body template:

```json
{
    "hours_selection": {
        "type": "auto",
        "mode": "share",
        "share_factor": "0.5",
    },
    "wallet": {
        "id": "$wallet_id",
        "password": "$password"
    },
    "to": [{
        "address": "$dst",
        "coins": "$coins"
    }]
}
```

You must use a string for `"coins"` instead of an integer measured in "droplets" (the smallest unit of currency in Skycoin, 1/1000000 of a skycoin).
For example, if you sent 1 Skycoin with `/api/v1/spend` you would have specified the `coins` field as `1000000`.
Now, you would specify it as `"1"`.

Some examples:

* 123.456 coins: before `123456000`, now `"123.456"`
* 0.1 coins: before `100000`, now `"0.1"`
* 1 coin: before `1000000`, now `"1"`

Extra zeros on the `"coins"` string are ok, for example `"1"` is the same as `"1.0"` or `"1.000000"`.

Only provide `"password"` if the wallet is encrypted. Note that decryption can take a few seconds, and this can impact
throughput.

The request header `Content-Type` must be `application/json`.

The response to `POST /api/v1/wallet/transaction` will include a verbose decoded transaction with details
and the hex-encoded binary transaction in the `"encoded_transaction"` field.
Use the value of `"encoded_transaction"` as the `"rawtx"` value in the request to `/api/v1/injectTransaction`.

## Migration from /api/v1/explorer/address

The `GET /api/v1/explorer/address` was deprecated in v0.25.0 and removed in v0.26.0.

To migrate from it, use [`GET /api/v1/transactions?verbose=1`](#get-transactions-for-addresses).

`/api/v1/explorer/address` accepted a single `address` query parameter. `/api/v1/transactions` uses an `addrs` query parameter and
accepts multiple addresses at once.

The response data is the same but the structure is slightly different. Compare the follow two example responses:

The transaction data is wrapped in a `"txn"` field. A `"time"` field is present at the top level. This `"time"` field
is either the confirmation timestamp of a confirmed transaction or the last received time of an unconfirmed transaction.
