API ratelimiting, setting extra headers X-RateLimit-Limit X-RateLimit-Remaining X-RateLimit-Reset

[asarnoldas]

I am searching for API ratelimiting and can't find anything...

Is it possible to handle all of this in nginx? ( Seting/evaluating headers,
limiting connection, IP whitelisting ) ?

I want to throttle access to our API and send extra headers, based on the
limit say 100 req / minute for 1 IP you would get a 429 HTTP error code (
Too many requests ) and extra header X-RateLimit-Reset: would state how much
time left until limit will expire.

X-RateLimit-Limit: 60
X-RateLimit-Remaining: 56
X-RateLimit-Reset: 54

Like github does and documents it:
