Rate Limiting  [Go SDK]

In order to provide service stability, Frontier limits the number of requests a client (single IP) can perform within a one hour window. By default this is set to 3600 requests per hour—an average of one request per second. Also, while streaming every update of the stream (what happens every time there’s a new ledger) is counted. Ex. if there were 12 new ledgers in a minute, 12 requests will be subtracted from the limit.

Frontier is using GCRA algorithm.

Response headers for rate limiting

Every response from Frontier sets advisory headers to inform clients of their standing with rate limiting system:

Header Description
X-RateLimit-Limit The maximum number of requests that the current client can make in one hour.
X-RateLimit-Remaining The number of remaining requests for the current window.
X-RateLimit-Reset Seconds until a new window starts.

In addition, a Retry-After header will be set when the current client is being throttled.
