## 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 veriffr-french-address-autocomplete-api-9b45e820
```

Example prompt: Can you look up the full address details for '10 Rue de Rivo' in Paris — I need the postcode, city, and coordinates, and show me the top 3 matches?

## When to prefer this

Choose this endpoint when you need to autocomplete, geocode, or validate French addresses specifically, and want a pay-per-call model with no account or API key setup. It is ideal for AI agents needing lightweight, on-demand French address resolution without committing to a subscription. Prefer it over general geocoding APIs when you only need France coverage and want USDC micropayment billing on Base.

## Known failure modes

- Query string shorter than 3 characters returns an error or empty result
- No matching addresses found returns an empty results array
- Payment failure (insufficient USDC balance) blocks the request with a 402 response
- Invalid or malformed query parameter returns a validation error
- Network timeout from upstream address database

## How this service works

Verify French companies, EU VAT numbers, and addresses from one API. Pay per call with USDC on Base via x402. No account, no API key.

## Output

Returns a JSON object with the matched address label, street name, house number, city, postcode, latitude, longitude, and a confidence score (0–1). Up to the requested number of matches (default 5, max 10) are returned, ranked by relevance score.
