French Reverse Geocoding: Nearest Address to a Coordinate (IGN Géoplateforme)

geopf/reverse-geocode

Reverse geocodes a point in France with the Géoplateforme (IGN) geocoder: returns the nearest addresses as GeoJSON points, each with the normalised address label, postcode, commune name and INSEE code, department and region context, and the distance in metres from the point. A point with no address nearby returns an empty list. Covers France. Data from the Géoplateforme, Licence Ouverte 2.0 (Etalab), or the dataset's own licence where it states one, passed through unmodified and served by Eden Engine; not an official IGN product.

// 1. search: find the tool
omnial_search({ query: "what you need" })

// 2. inspect: price and input schema
omnial_inspect({ tool: "geopf/reverse-geocode" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "geopf/reverse-geocode" })

// 4. run: price the exact call first, then run it
omnial_execute({ tool: "geopf/reverse-geocode", input: { /* see input_schema */ }, dry_run: true })
