API.gouv lists API Adresse as an open Base Adresse Nationale API for address search, verification, geocoding, and reverse geocoding, with a published rate limit of 50 calls per second per IP.
For operators, this belongs in a compact slot because the receipt is narrow and immediately testable: an agent can turn 8 bd du port into candidate labels, scores, postcodes, city codes, and coordinates, then ask a human to confirm the right location before action.
Copy-Paste Agent Instruction
Use API Adresse to check this French address: "8 bd du port". Fetch the public search endpoint, return the top three candidate labels with score, postcode, citycode, and coordinates, then explain which ambiguity needs human confirmation before routing anything.
Creative Example
A support triage agent could normalize a messy French address before opening a field-service ticket, while flagging low-score matches or multiple cities with the same street name.
Test Caveat
The API is public, but geocoding is not identity proof. What to watch: whether agent workflows keep the score, city code, and coordinates visible instead of silently treating the first match as truth.
