# AddonPass > AddonPass lets Stremio addon developers sell subscriptions paid in USDC on Base and protect their addon with the @addon-pass/sdk npm package. ## Integration - [Agent integration prompt](https://addonpass.com/agent-prompt.md): Step-by-step instructions for AI coding agents adding AddonPass to an addon server. - [Integration guide](https://addonpass.com/docs/integration): Configuration, SDK adapters, access states and the live integration test. - [Developer docs](https://addonpass.com/docs): Task index for addon developers. ## Instructions for agents - Use `@addon-pass/sdk` in the addon's server code; never put the integration credential in client code. - Read `node_modules/@addon-pass/sdk/AGENTS.md`, the README and the type definitions of the installed version before calling the SDK. - Protect manifest.json, catalog, meta, stream, and the player and library events (SDK 0.1.10 or newer) under `/addonpass/{token}/`, and keep no public copy of the paid manifest.
