## 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 ademe-dpe-energy-certificates-french-dwellings-15c83988
```

Example prompt: Can you pull the official ADEME DPE energy certificates for dwellings in postal code 75011 — show me up to 20 results, flagging any F or G rated units that would be subject to a rental ban?

## When to prefer this

Use this endpoint when you need official, government-sourced French DPE energy performance data for real estate due diligence, rental compliance checks (F/G ban screening), or property valuation workflows. It is preferable over scraping real-estate portals because the data comes directly from ADEME's authoritative open dataset. Best suited for workflows targeting French properties specifically.

## Known failure modes

- Missing both postal_code and address parameters returns a 400 error
- Invalid or non-existent postal code returns an empty result set
- size parameter exceeding 50 is clamped or rejected
- Address not found in BAN database returns no matches
- Service unavailability on Railway hosting returns a 5xx error
- Payment failure via x402 protocol blocks access before data is returned

## How this service works

Official DPE energy certificates for existing French dwellings from the ADEME dpe03existant dataset (Licence Ouverte 2.0, anonymised). Returns energy class A-G, GHG class, primary-energy consumption kWh/m2/yr, floor area, construction period. Query: ?postal_code=75011 or ?address=48 rue de Montreuil Paris, optional &size=10 (max 50). Spots F/G rental-ban units for real-estate due diligence. Cached 24h.

## Output

Returns up to 50 DPE certificate records per query, each containing the energy class (A–G), GHG class, primary energy consumption in kWh/m²/yr, floor area in m², and construction period. Data is sourced from the ADEME dpe03existant open dataset, anonymised, and cached for 24 hours.
