Technical details
Endpoint
POSThttps://x402.forgemesh.io/zip-code-lookup?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to resolve a postal/zip code to human-readable location data (city, state, coordinates) for address validation, geo-enrichment, shipping estimation, or tax jurisdiction determination — especially when handling international postal codes across 60+ countries. Prefer this over full geocoding APIs when the input is specifically a postal code rather than a full street address.
Side effects
- Unknown or invalid postal code returns a 404 unpaid response
- Unsupported country code may return no result or error
- Malformed postal code format may yield no match
- Payment failure ($0.003 USDC) blocks the response
- Cached result may be up to 24 hours stale for recently updated postal areas
