How this service works
Pay-per-call APIs for AI agents — x402 protocol, USDC on Base, no account needed.
Output
A list of recorded property transactions from the French DVF (Demande de Valeurs Foncières) dataset near the queried address, including actual sale prices paid, transaction dates, property surface areas, and property types (apartment, house, etc.) — all sourced from official government records.
Example use cases
Apartment purchase price benchmarking
“I'm considering buying an apartment near 45 avenue Jean Jaurès Lyon 69007 — can you look up what similar properties have actually sold for in that area using official French transaction records?”
Rental yield estimation for investors
“I need the real sale prices for properties around 8 boulevard Haussmann Paris 75009 from the DVF dataset so I can estimate realistic capital values and rental yields for my investment analysis.”
Notarial due diligence on a property sale
“We're finalizing a property deal near 22 rue du Faubourg Saint-Antoine Paris 75012 and I need the official recorded transaction prices for comparable sales nearby to confirm our valuation is in line with the market.”
Technical details
Endpoint
POSThttps://api.x-402.online/v1/fr/immo?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need verified, official French property transaction data (actual prices paid, not listings) from the government DVF registry. It is ideal for property valuation, market analysis, comparable sales research, or due diligence on French real estate. Prefer this over scraping listing sites or using estimated valuations when ground-truth transaction data is required.
Side effects
- Address not found or not geocodable — returns empty results or error
- No transactions recorded near the address within the DVF dataset coverage period
- Address outside France — endpoint only covers French territory
- Malformed address input — API returns validation error
- Sparse rural areas may return very few or no comparable transactions
