Our public API is guarded by a rate limiter using several techniques to prevent abuse. Calls to this API that are rate limited will return a
429 status code along with relevant headers that indicate the remaining quota (
X-RateLimit-Remaining-IP) and how long to wait until the next window specified in seconds (
X-RateLimit-Reset-Seconds-IP). When rate limited, users should retry after a number of seconds equal to or greater than the maximum time of the last two "X-RateLimit-Reset-Seconds-XXX" headers.
API rate limiting and SDKs
Rate-limiting only applies to this public API and does not affect the API used by the SDKs to serve feature evaluations.
