API calls are rate limited to prevent bursts of incoming traffic to help maximize stability. If a client is rate limited the API will return a 429 status code.

Three headers are returned with every API response that indicate how close the client is to being rate limited and when the limit will reset.

x-rate-limit-limitThe total limit for the given period of time.
x-rate-limit-remainingThe amount of requests remaining out of the total limit.
x-rate-limit-resetThe timestamp, in epoch, when the limit will reset to the value in x-rate-limit-limit
x-rate-limit-limit: 1000
x-rate-limit-remaining: 995
x-rate-limit-reset: 1619380800
