The API has a fixed number of requests of 250,000 requests per month, with a maximum burst of 20 requests per minute, spread over that minute.
When this is exhausted, the API will simply cease allowing calls to take place. If you find your need to be greater than this then please reach out with your use case and our engineers can help with some optimisation suggestions
We do reserve the right to adjust the rate limit for given endpoints to provide a high quality of service for all API customers.
