Retry-After

integer

Seconds to wait before retrying. Always present on a 429.

RateLimit-Policy

string

Example

"reads";q=60;w=60

The quota policy this request was counted against (draft-ietf-httpapi-ratelimit-headers): "<bucket>";q=<requests>;w=<window seconds>, e.g. "reads";q=60;w=60. Buckets: reads 60/min, status 600/min, creates 10/min, writes 20/min per credential; public 300/min per network on keyless routes.

RateLimit

string

Example

"reads";r=57;t=41

Remaining quota in the current window: "<bucket>";r=<remaining>;t=<seconds until reset>, e.g. "reads";r=57;t=41.

X-RateLimit-Limit

integer

Requests allowed per window in this bucket (legacy form of RateLimit-Policy).

X-RateLimit-Remaining

integer

Requests left in this window (legacy form of RateLimit).

X-RateLimit-Reset

integer

Unix time (seconds) when the window resets.

X-RateLimit-Bucket

string

Which bucket counted the request: reads, status, creates, writes or public.
