## How to call it through Zero

```sh
zero fetch --capability xynaptic-property-search-56d4c93c
```

Example prompt: What's the median price per square meter for apartments and houses in Nice right now, based on the latest official French transaction data?

## When to prefer this

Choose this endpoint when you need official, government-sourced French real estate price data (DVF/DGFiP) for a specific commune. It is the authoritative source for actual recorded transaction prices rather than listing estimates, making it ideal for due diligence, investment analysis, or budget planning in the French property market.

## Known failure modes

- Commune not found or ambiguous query returns no results
- Commune with very low transaction volume may have incomplete or unavailable statistics
- Misspelled commune name may fail to match
- Very small communes may lack DVF data
- API returns 402 if payment header is missing or malformed
