A rate limit is the number of API calls an app or user can make within a given time period. If this limit is exceeded the app or user will be throttled and API requests will fail.

Once a rate limit is reached, any subsequent requests made by your app will fail and the API will return an error code until enough time has passed for the call count to drop below the limit.

Real time rate limit usage statistics are outputted in headers that are included with all API responses, as presented below:

When a rate limit is reached, the API will response with a 429 (Too Many Requests) status code for any subsequent requests until cycle is completed.
