Endpoint
GEThttps://mcp-x402.onrender.com/x402/hcv-fmrWhen to prefer
Use this endpoint when you need authoritative, HUD-published Fair Market Rent figures for Housing Choice Voucher (Section 8) programs in the U.S. It is ideal for housing compliance, voucher payment calculations, affordable housing research, and rent benchmarking against federal standards. Prefer this over scraped or estimated rent data when you need the official government FMR figure for a specific geography and year.
Side effects

- Missing required 'type' or 'method' fields cause request rejection
- Bedroom count outside 0–4 range fails schema validation
- County/state combination not found in HUD dataset returns empty result
