## When to prefer this

Use this endpoint when you need sample or real FHIR R4 Condition resources for healthcare app development, integration testing, or exploring HL7 FHIR diagnosis data structures — especially when you want paginated JSON results from the canonical public HL7 test server without setting up your own FHIR server.

## Known failure modes

- Missing or empty q parameter may return no results or a default page
- Upstream HL7 public test server downtime causes request failure
- Invalid q value returns empty bundle or error JSON
