How this service works
Postal code API: city, state, and coordinates for any zip/postal code in 60+ countries, and reverse place-to-codes search. For address validation, shipping, and geo-enrichment agents.
Output
Returns the city name, state/province, and geographic coordinates (latitude/longitude) associated with the given postal/zip code. May also support reverse lookup returning multiple postal codes matching a place name.
Example use cases
Example prompt
“What city and state is zip code 77001 in, and can you also get me the coordinates for it? It's a US postal code.”
Technical details
Endpoint
POSThttps://x402.forgemesh.io/postal-code-lookupWhen to prefer
Use this endpoint when you need to resolve a zip or postal code to a city, state, and lat/lng coordinates for any of 60+ countries, especially for address validation, shipping workflows, or geo-enrichment pipelines. Prefer this over full geocoding APIs when you only have a postal code and need a fast, cheap structured lookup without a full address.
Side effects
- Invalid or non-existent postal code returns error or empty result
- Unsupported country code results in no data
- Missing required 'code' field causes validation error
- Ambiguous place name in reverse search may return multiple or no results
- Payment failure or insufficient USDC balance blocks the request
