Saylor Innovations France Address Geocoder

Choose this endpoint when you specifically need French address geocoding backed by the official Base Adresse Nationale dataset, which is the authoritative French government address registry. It is ideal when you need administrative metadata like INSEE commune codes, department, and region alongside coordinates — data that generic global geocoders often omit for France. Prefer it over general-purpose geocoders for French-language addresses, French administrative workflows, or when INSEE codes are required.

• No results found for ambiguous or misspelled address — returns empty results array
• Non-French addresses return no results as the BAN only covers France
• Missing required 'q' query parameter returns an error
• Very short or vague queries may return low-confidence or irrelevant results
• Service unavailable or payment failure returns HTTP 402 or 5xx error
