The Orb API imposes safeguards to help ensure service availability against bursts of incoming traffic. Orb is implemented in the critical path for many of our customers and our rate limits are designed with that consideration in mind:
CategoryApplicable endpointsLive mode limitTest mode limitTrial limit

Read-only queriesAll GET requests exclusive of the Analytics scope.100 queries per second50 queries per second10 queries per second

This quota can be increased significantly upon request. For information regarding support for higher event ingestion volumes, see the guide on high throughput ingestion.		2,000 events ingested per minute100 events ingested per minute

Handling rate limits

In the event of a 429 Too many requests error, we recommend you retry the request with an exponential backoff.
