RedirHub limits API requests on a per account basis to a reasonable amount - a daily limit of 250,000 requests and a burst limit of 200 requests per 60 seconds.
If your client reaches our rate limiting, you will receive a
429 Too Many Requests
error with additional rate limiting information in the headers of the response.
The number of requests that may originate from your client during the set period.
The number of requests remaining until the reset cycle.
The epoch timestamp when the request limit will be reset.
You can use the headers from the response programatically to throttle your own requests. These headers are only returned if you have reached the request limit.
