For developers: download the machine-readable API definition — openapi.json (OpenAPI 3 format).

This file describes every endpoint, its parameters and its response format in a standard layout that API tools understand. You can import it into a tool such as Postman, Insomnia or Swagger UI to explore the API and try calls without writing any code, or use it to automatically generate a client library in most programming languages. If you are just reading these pages by hand, you don't need it — the documentation below covers everything.
