Limits
Rate limits
Requests are limited with token buckets: each allows a steady rate and a short burst above it. A request must fit in every bucket that applies.
A request over a limit is answered with
429, error code rate_limited and a retry-after header with the number of seconds to wait. Wait at least that long before retrying, and add jitter when several workers share a key. To read a lot of history, ask for large pages (limit up to 10,000) rather than many small ones.
