How this service works
200 pay-per-call tools for AI agents, from $0.001 per request in USDC on Base or Solana with x402. No account, no API key.
Output
Returns a JSON object with the country, postal code, and an array of matching places. Each place includes its name, region (e.g. state or province), latitude, and longitude as strings.
Example use cases
Enrich customer address with city name
“I have a customer record with country 'de' and postal code '10115' — can you look up what city and region that corresponds to, along with the coordinates?”
Validate delivery address region
“We received an order with zip code 33101 in the US — what place and region does that postal code map to so I can confirm the delivery area?”
Geocode postal code for mapping
“I need the latitude and longitude for postal code 75001 in France so I can pin it on a map — can you look that up?”
Technical details
Endpoint
GEThttps://fastx402.tools/postal-place-lookup?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, no-account postal code to place-name/coordinates lookup without setting up an API key. It is ideal for enriching records with city/region names or rough coordinates from a postal code, especially when cost per call matters and you want per-request micropayments via USDC. Prefer this over full geocoding APIs when you only have a postal code and country and don't need street-level precision.
Side effects
- Invalid or non-existent postal code returns an empty places array
- Unsupported or misspelled country code may return an error or empty result
- Missing required query parameters (country or postal_code) results in a validation error
- Payment failure via x402 protocol results in a 402 response before the lookup is attempted
