## 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-reverse-geocoder-lat-lon-to-address-46c2a90a -d '<json body>'
```

Example prompt: What is the French postal address at coordinates 48.8566° N, 2.3522° E?

## When to prefer this

Use this endpoint when you need to resolve GPS coordinates to a human-readable French address, especially when coverage of French overseas territories (Guadeloupe, Martinique, Réunion, etc.) is required. Prefer this over generic geocoding APIs when operating within the French administrative address system.

## Known failure modes

- Coordinates outside France or overseas territories return no result or an error
- Missing lat or lon query parameter returns a 400 bad request
- Coordinates in the ocean or unpopulated areas may return no matching address
- Payment not completed results in a 402 Payment Required response

## Output

A structured French address corresponding to the given coordinates, including street name, city, postal code, commune, and department. Covers metropolitan France and overseas territories (DOM-TOM).
