How this service works
Pay-per-call APIs for AI agents — x402 protocol, USDC on Base, no account needed.
Output
Returns a JSON array of results, each containing the property address, its DPE energy efficiency label (A through G), and its GES greenhouse gas emission label (A through G), sourced from the French government's ADEME database.
Example use cases
Check energy rating before renting
“I'm considering renting an apartment at 45 Avenue Jean Jaurès, 69007 Lyon — can you look up its DPE energy label and GES rating so I know how efficient it is?”
Real estate listing enrichment
“I'm preparing a property listing for 8 Rue des Lilas, 33000 Bordeaux — can you fetch its official DPE and GES labels from the government database so I can include them in the ad?”
Compare energy efficiency of two homes
“Can you get the DPE energy labels for 3 Rue Molière, 31000 Toulouse and tell me whether it qualifies as a well-rated property according to French standards?”

Endpoint
GEThttps://x402-farm.vercel.app/v1/fr/dpeWhen to prefer
Use this endpoint when you need official French DPE (Diagnostic de Performance Énergétique) energy and GES ratings for a specific property address, especially in real estate research, compliance checks, or listing enrichment workflows. It is a pay-per-call service requiring no account setup, making it ideal for sporadic or agent-driven lookups using USDC on Base via the x402 protocol. Prefer this over scraping real estate portals when you need authoritative, government-sourced data.
Side effects
- Address not found in ADEME database — empty results array returned
- Ambiguous or malformed address yields no matches
- Property predates mandatory DPE certification — no record available
- Payment not processed via x402 — 402 Payment Required response before data is returned
- Network timeout or upstream ADEME API unavailability
