Maximum sustainable number of request allowed each minute per account. This rate limit protects PAPI resources from being exhausted by single users. Once you exceed the limit, you receive the 429 error. If you call PAPI using multiple API clients within the same account, the rate limit applies globally to all API clients.
This API also provides a burst limit that specifies how many requests you can make in excess of the imposed rate limit. The one-time burst limit is 1000 requests. Once you consume all available resources, the burst capacity increases steadily by 100 requests every minute, until it reaches its initial maximum limit of 1000.
