## When to prefer this

Use this endpoint when you need to retrieve FHIR-compliant Location resource data from the standard HL7 FHIR R4 test server in JSON format, particularly for healthcare interoperability testing, HL7 integration work, or when you need paginated location records in the FHIR resource schema rather than raw address lookups.

## Known failure modes

- Empty result set if no FHIR Locations match the query string
- Invalid or missing q parameter may return an error or default empty page
- Public test server downtime may cause 503 or connection errors
- Malformed query strings may result in 400 Bad Request
- Rate limiting or payment failure may block access (402 Payment Required)
