We enforce a rate limit on the number of HTTP requests that can be made in a given period. When the limit is reached, our Premium Bank API will return a 429 Too Many Requests error.
To allow you to handle this rate limiting programmatically, the following headers are sent with every response:
RateLimit-Limit: total number of available requests between two quota resets;RateLimit-Remaining: number of available requests until the quota is reset;RateLimit-Reset: time remaining (in seconds) until the quota is reset.
