## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability x402-farm-french-dpe-lookup-353a36de
```

Example prompt: What are the DPE energy label and GES greenhouse gas rating for the property at 12 Rue de la Paix, 75001 Paris?

## When to prefer this

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.

## Known failure modes

- 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

## How this service works
