## 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 france-communes-by-postal-code-48cd4e04 -d '<json body>'

## When to prefer this

Use this endpoint when you need to resolve a French postal code to one or more commune (municipality) names — particularly useful for address validation, geospatial enrichment, or when building French address forms. Prefer this over generic geocoding APIs when you specifically need the official French administrative commune list, as it draws from the authoritative government geo.api.gouv.fr source.

## Known failure modes

- Invalid or non-existent postal code returns empty array or error
- Postal code with no matching communes returns empty results
- Malformed query parameter returns 400 or empty response
- Non-French postal codes are not supported
