Here is some information regarding our API rate limit policy:
- we do not rate limit on datapoint/metric submission - the limits you'd encounter would be based on your agreement
- rate limit for event submission is 1000 per aggregate per day per organization. An aggregate is a group of similar events as described here
- rate limit for the query_batch API call is 300 per hour per organization, it can be extended on demand
- rate limit for the query_snapshot API call is 60 per hour per organization, it can be extended on demand
It's possible to know how close you are to your limit by checking the headers.
