The Problem

There are 10,000+ MCP servers. Most are hobby-quality because developers can't earn from them. Agents can discover tools but can't pay for them. There's no commerce layer.

The Solution: Agent Bazaar

A billing proxy that sits between agents and MCP servers. Providers set pricing, agents pre-fund balance, every call is metered with sub-cent precision.

# 1. Discover tools (no auth required)
curl https://noui.bot/api/bazaar/catalog

# 2. Call any tool through the billing proxy
curl -X POST https://noui.bot/api/bazaar/proxy \
  -H "Authorization: Bearer bz_your_key" \
  -d '{"tool_name":"wallet.balance","input":{"wallet":"0xAgent1"}}'

# 3. Check your usage
curl https://noui.bot/api/v1/bazaar/usage/summary \
  -H "Authorization: Bearer bz_your_key"

Live now: 14 tools · 6 providers · 10% platform fee · Sub-cent metering · Stripe Connect payouts

TypeScript SDK

npm install @forthebots/bazaar-sdk

import { Bazaar } from '@forthebots/bazaar-sdk';

const client = new Bazaar({ apiKey: 'bz_your_key' });

// Discover tools
const { tools } = await client.catalog.list();

// Call a tool (metered + billed)
const result = await client.tools.call('wallet.balance', { wallet: '0x...' });
console.log(result.meta.cost_cents); // $0.05

// Check balance
const { balance } = await client.balance.get();

For MCP Server Providers

Turn your MCP server into a revenue stream in 2 minutes:

1. Register: noui.bot/providers/register or POST /api/bazaar/register-provider
2. Add tools: POST /api/bazaar/tools with pricing
3. Get paid: Connect Stripe, earn 90% of every call
4. Monitor: noui.bot/providers/dashboard

# Register
curl -X POST https://noui.bot/api/bazaar/register-provider \
  -H "Content-Type: application/json" \
  -d '{"name":"My Tools","email":"dev@example.com","endpoint_url":"https://my-server.com/mcp"}'
# Returns: { "api_key": "bz_abc123..." }

For Agent Developers

One API key for thousands of tools:

1. Register: noui.bot/developers/register or POST /api/bazaar/register-consumer
2. Browse: GET /api/bazaar/catalog
3. Call: POST /api/bazaar/proxy — metered, billed, retried on 5xx
4. Monitor: noui.bot/developers/dashboard
