## When to prefer this

Use this endpoint when you need sample or test HL7 FHIR R4 Coverage (insurance) resources in standard Bundle format — ideal for FHIR integration testing, healthcare app prototyping, or exploring FHIR insurance data structures. Prefer this over general REST APIs when you specifically need FHIR-compliant Coverage resource data.

## Known failure modes

- Invalid or missing q parameter returns an error or empty Bundle
- Non-integer q value may cause a bad request response
- FHIR server unavailability returns a 5xx error
- q value too large may time out or return partial results
- Malformed response if upstream FHIR server returns unexpected data
