How this service works
Official French administrative reference from geo.api.gouv.fr (INSEE/IGN data). Look up communes by ?cp=31700 (postal code), ?code=31056 (INSEE), ?nom=Blagnac (fuzzy name) or ?lat=43.63&lon=1.37 (commune containing a point). Returns up to 20 communes with name, INSEE code, population, postal codes, departement, region and EPCI. The postal-to-INSEE mapping is the pivot key for joining French territorial datasets. Cached 7 days.
Output
Returns up to 20 matching communes, each with name, INSEE code, population, list of postal codes, département code and name, région code and name, and EPCI identifier. Response is cached for 7 days.

Technical details
Endpoint
GEThttps://x402-datashop-production.up.railway.app/v1/fr/communesWhen to prefer
Use this endpoint when you need authoritative French commune reference data including the postal-to-INSEE code mapping, which is the canonical join key for French territorial datasets. Prefer this over general geocoding APIs when you specifically need INSEE codes, EPCI identifiers, or French administrative hierarchy (département/région). Ideal for enriching addresses, validating French postal codes, or joining INSEE demographic datasets.
Side effects
- No commune found matching the provided postal code, INSEE code, name, or coordinates — returns empty results array
- Invalid or malformed query parameter (e.g. non-numeric lat/lon) — may return 400 or empty results
- Point coordinates that fall outside France or in the sea return no matching commune
- Fuzzy name search with very ambiguous input may return unexpected communes
- Upstream geo.api.gouv.fr unavailability causes proxy errors
