## How to call it through Zero

```sh
zero fetch --capability greeneris-french-address-geocoder-fd76bd0b
```

Example prompt: Can you geocode the French address '8 boulevard du Port, 80000 Amiens' and give me its exact coordinates and official INSEE city code?

## When to prefer this

Use this endpoint when you need authoritative, official French address geocoding backed by the national BAN registry (INSEE/IGN). Prefer it over generic geocoders when you need INSEE city codes, official French address labels, or high-confidence normalization of French addresses for compliance or business verification workflows. It is pay-per-call with no account setup required, making it ideal for AI agents with sporadic or one-off geocoding needs within France.

## Known failure modes

- No match found: matches array is empty with count 0 if the address is outside France or too ambiguous
- Invalid coordinates for reverse mode: missing lat or lon returns a 400-level error
- Limit out of range: values outside 1–10 may be rejected or clamped
- Payment required: HTTP 402 with a machine-readable USDC quote if x402 payment header is absent
- Rate or quota issues if the underlying BAN API is temporarily unavailable

## How this service works

French address geocoding on the official Base Adresse Nationale (api-adresse.data.gouv.fr, Etalab/IGN, continuously updated). Forward: ?q=8 boulevard du port amiens with optional &type=housenumber|street|locality|municipality &citycode=80021 (INSEE filter). Reverse: ?lat=49.897&lon=2.290. &limit=1-10 (default 3). Each match returns normalized label, confidence score, lat/lon, street, postcode, city, INSEE citycode and context. No match returns 400 (not billed). Cached 24h.

## Output

A JSON object with mode, query, source attribution, and a matches array. Each match includes latitude, longitude, formatted label, street name, city, postcode, INSEE citycode, Département context, match type (housenumber/street/locality/municipality), and a confidence score (0–1).
