## 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 french-dvf-real-estate-sale-prices-by-commune-f3aa814c -d '<json body>'
```

Example prompt: Can you pull up all the real estate sales from the DVF for commune INSEE code 69123 (Lyon 3rd) for the year 2022 — I want to see the sale prices, surface areas, and property types?

## When to prefer this

Use this endpoint when you need raw, individual DVF transaction records for a specific French commune and year — ideal for building price histories, feeding AVM models, or auditing sales. Prefer this over the AVM or investment scorecard endpoints when you want granular transaction-level data rather than aggregated estimates.

## Known failure modes

- Missing or invalid INSEE code returns an error or empty result
- Invalid or out-of-range year returns no data
- Commune with no recorded sales in the given year returns an empty list
- Payment failure (insufficient USDC balance) blocks the request
- Rate limiting or network timeout returns a 402 or 5xx error

## Output

A list of real property sale transactions for the specified French commune and year, each including the transaction date, sale price (in euros), surface area (in m²), and property type (apartment, house, land, etc.), sourced directly from the official French DVF (Demandes de Valeurs Foncières) registry.
