Technical details
Endpoint
GEThttps://api.xynaptic.io/v1/property-transactions?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need official, government-sourced French real estate transaction data (DVF registry) with clean structured fields including price per sqm. Prefer this over scraped or estimated property databases when accuracy and official provenance matter, particularly for French cities. Best suited for market analysis, benchmarking, investment research, or any use case requiring verified sale prices rather than listing prices.
Side effects
- City name not found or misspelled — returns empty result set or 404
- Invalid property type value — returns error or empty results
- Limit parameter out of range — may return default count or error
- No transactions available for the specified city/type combination — empty array returned
- Rate limiting or payment failure if x402 micropayment is not properly handled
