Rate Limits

The PHC micro-service platform processes over 20 million API requests a day. Reasonable API Rate Limits are in place to impose soft limits on the platform. These limits allow organizations and customers on the Precision Health Cloud to have adequate capacity and provide protection against denial of service attacks, accidental bursts, and unoptimized single/batched API calls.
