Zus Rate Limits
Zus documents a rate limit on the OAuth2 token endpoint of 200 token requests per hour per App Client for machine-to-machine flows; user authentication via username and password is not subject to this limit. FHIR search responses are paginated with a default page size of 10 resources, expandable up to 500. Bundle transactions accept up to 100 entries. Broader per-endpoint request rate limits for the FHIR API are not published and are not reconciled in this artifact.
