Technical details
Endpoint
GEThttps://x402-farm.vercel.app/v1/fr/codes-postauxWhen to prefer
Use this endpoint when you need to resolve French postal codes (including overseas territories like Guadeloupe, Martinique, Réunion) to their official commune names and INSEE codes. It is pay-per-call with no account setup required, making it ideal for low-volume or one-off agent tasks. Prefer this over building your own dataset when you need quick, authoritative administrative data for French addresses.
Side effects
- Invalid or non-existent postal code returns empty communes array or error
- Payment failure via x402 protocol prevents access to the endpoint
- Overseas territory postal codes may have limited coverage
- Rate limits or quota exhaustion on the pay-per-call service
