## When to prefer this

Use this endpoint when you need authoritative, cryptographically verifiable HUD Fair Market Rent figures for a specific metro area and bedroom size — particularly for affordable housing underwriting, LIHTC rent limit compliance, Section 8 voucher eligibility checks, or any workflow requiring audit-grade provenance on government rent data.

## Known failure modes

- Invalid or unrecognized metro area name — returns error or no match
- Bedroom count outside 0–4 range — schema validation error
- HUD dataset not yet updated for current year — may return prior year's FMR
- Network or payment authorization failure — no data returned
