The library transcript.

RateLimit The most restrictive policy that applied: "name";r=<requests left>;t=<seconds>, where t is the number of seconds until one more request is allowed (0 when the quota is full). Absent when no rate limiter ran for the request.
RateLimit-Policy The rate-limit policies that applied to the request, one "name";q=<burst>;w=<seconds> item per policy, for example "read";q=10;w=2, "account";q=20;w=2: q is the burst quota and w the seconds in which an empty quota refills. Sent on every authenticated response; absent when no rate limiter ran for the request, for example when it was rejected before the key was checked.
Request-Id ID of this request (req_ prefix), the same as request_id in an error body. It is also sent as X-Request-ID. Quote it when you contact support.
X-Client-Request-Id Your own X-Client-Request-Id request header, echoed back. It is sent only when the value you sent has 1-128 characters from A-Z a-z 0-9 . _ : -.
X-RateLimit-Limit Burst quota of the most restrictive policy (q in RateLimit-Policy). Absent when no rate limiter ran.
X-RateLimit-Remaining Requests left in the most restrictive policy (r in RateLimit). Absent when no rate limiter ran.
X-RateLimit-Reset Seconds until one more request is allowed in the most restrictive policy (t in RateLimit; 0 when the quota is full). It is a number of seconds, not a timestamp. Absent when no rate limiter ran.
