## When to prefer this

Use this endpoint when you need a quick, transparent, methodology-backed rent estimate for a French city without scraping live listings. Ideal for investment analysis, landlord pricing guidance, or due diligence calculations where an indicative figure from price-to-yield relationships is sufficient. Not suitable when a precise, current market listing price is required.

## Known failure modes

- Unsupported city name returns an error or null estimate
- Invalid or missing 'type' or 'surface' parameters cause a 400-level error
- Very small or unusually large surface values may yield unreliable estimates
- City names with accents or alternate spellings may fail to resolve
