## 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-house-price-lookup-by-d-partement-or-commune-08433ab8
```

Example prompt: What are the average and median property sale prices per square metre in Bordeaux — I have the INSEE commune code 33063.

## When to prefer this

Use this endpoint when you need authoritative French property price benchmarks at the commune or département level based on actual DVF transaction data. It is the right choice for French real estate research, property valuation context, or investment analysis — particularly when you have a specific INSEE commune code or département code. Prefer this over generic scrapers when you want structured, licensed open-data-backed price statistics with per-m² granularity.

## Known failure modes

- Invalid or unrecognised département code returns an error or empty result
- Malformed INSEE commune code (wrong digit count or non-existent code) returns no data
- Some overseas territories or very small communes may have insufficient sales data
- Network or payment failure via x402 returns HTTP 402 if payment is not processed

## How this service works

What is the average rent in an Irish area? What is the rent increase limit? What are house prices in a county? Pay-per-call Irish rent and property price data for agents and developers. x402 and MPP, MCP server, no API keys.

## Output

Returns the location name, administrative level (commune or département), mean price per m², median price per m², and total number of sales for apartments and houses combined, plus attribution to the DVF / data.gouv.fr source.
