French Address Search vs Wikidata

geo.api.gouv.fr's address search now redirects to Etalab's Base Adresse Nationale API at api-adresse.data.gouv.fr, which geocodes and reverse-geocodes French addresses down to the housing-unit level from the country's authoritative address registry. Responses come back as GeoJSON FeatureCollections scored by match confidence, and the service is free and keyless for reasonable use.

Wikidata's action API exposes the structured, multilingual knowledge base behind Wikipedia's infoboxes — entity search, full item/property retrieval, and SPARQL-style queries over billions of statements. All read operations (wbsearchentities, wbgetentities, wbgetclaims, and friends) are keyless; OAuth only comes into play for authenticated edits/writes, which this directory entry isn't about. CORS is opt-in per request via the documented `origin=*` query parameter, which returns a wildcard Access-Control-Allow-Origin.
