Technical details
Endpoint
POSThttps://api.x-402.online/v1/fr/estimation-immo?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, data-backed property price estimate for a specific French address, grounded in actual notarial sale records (DVF). Prefer it over generic real estate platforms when you need programmatic access to €/m² medians and ranges for appartement or maison types. It is especially useful for investment analysis, buyer/seller negotiation support, or enriching a broader French real estate dossier (complement it with DPE, risk, and KYB data from sibling endpoints).
Side effects
- Address not found or too ambiguous — returns error or empty comparables
- No DVF transactions found nearby — insufficient data for estimate
- Missing required query parameters (adresse, surface, or type) — returns 400-style error
- Address outside France — endpoint only covers French DVF data
- Payment not completed (402) — for non-free tier calls
