FAQ

What is a rate limit?

A cap on how many requests a client can make to an API within a specific time window.

What is burst size?

The maximum number of requests allowed in a short spike before throttling kicks in (token bucket model).

How is recovery time calculated?

burst_size ÷ (limit / window_seconds) — the time to refill tokens after a full burst.
