API

Rate limits and request size

Each key has a request rate limit, and public routes have a smaller one per address. Over the limit the API answers rate_limited with a Retry-After header saying how many seconds to wait. Bodies are limited to 256 KB on API routes, so media goes to storage through a signed address.

Key routes: limited per key; the numbers are in the security scheme of the reference.
Public routes and free tools: 30 requests a minute and 1,000 a day per address, with no key.
Bodies: 256 KB on API routes. Larger files use media uploads.

Back off for the number of seconds in Retry-After, then retry with the same Idempotency-Key.
