+# AGENTS.md — uapi-browser-sdk
+
+This file tells AI coding agents how to use the **official browser /
+vanilla-JS SDK** for the [uapis.cn](https://uapis.cn) public API platform.
+
+## What this package is
+
+Browser-first, dependency-free TypeScript client for UAPI. Built on the
+native `fetch` API, ships an ESM bundle, and works equally well from a
+`<script type="module">` tag, a Vite/Next/Remix project, or a Cloudflare
+Worker. Generated from the live OpenAPI 3.1 spec at
+<https://uapis.cn/openapi.json>.
+
+## Install
+
+```bash
+npm i uapi-browser-sdk
+# or with pnpm / yarn
+```
+
+CDN:
+
+```html
+<script type="module">
+  import { UapiClient } from "https://esm.sh/uapi-browser-sdk";
+  const client = new UapiClient("https://uapis.cn");
+  console.log(await client.misc.getMiscWeather({ city: "北京" }));
+</script>
+```
+
+## Quick start
+
+```ts
+import { UapiClient } from "uapi-browser-sdk";
+
+const client = new UapiClient("https://uapis.cn");
+const weather = await client.misc.getMiscWeather({ city: "北京" });
+console.log(weather);
+```
+
+The client is grouped by tag (`misc`, `network`, `text`, `image`, `social`,
+`translate`, `search`, …) and each method name matches the underlying
+`operationId`, camelCased.
+
+## Authentication
+
+Free-tier endpoints work with no key. Paid endpoints take a key:
+
+```ts
+const client = new UapiClient("https://uapis.cn", { apiKey: "sk_…" });
+```
+
+> **Warning.** Putting an API key inside a public web page exposes it to
+> anyone who reads the JS bundle. For browser-side calls to paid
+> endpoints, prefer a thin server-side proxy that injects the key.
+
+## Errors
+
+Methods throw a typed `UapiApiError` on non-2xx responses. The error
+carries `code`, `error`, and `requestId` fields. Surface `error` verbatim.
+
+## Rate limits
+
+Headers `X-RateLimit-Limit`, `X-RateLimit-Remaining`, `X-RateLimit-Reset`,
+`Retry-After` are exposed via `error.response.headers` (and on success
+responses via the optional `withResponse` overload). Honor them.
