Our REST API documentation is now **automatically updated** with changes to our API.

Developers can use our REST API to extend the Vercel platform and programmatically augment their workflows. After every change to our API repository, a new version of the documentation is automatically generated. This includes all API endpoints and the correct fields and types used. Starting today, more endpoints are listed and all parameters are now documented.

Check out [the improved documentation](https://vercel.com/docs/rest-api).
