How this service works
108+ receipt-backed x402 work products for AI agents. Clear prices, spend caps, buyer metadata, and structured results over Base USDC.
Output
Returns geographic and administrative data for the given postal code, including city name, state or region, and potentially geographic coordinates. The response is a JSON object with location fields derived from official postal data.
Example use cases
Validate e-commerce shipping address
“I have a customer order with postal code SW1A 1AA in GB — can you confirm what city and region that maps to so I can verify the shipping address?”
Enrich user profile with location
“A user signed up with postal code 10001 and country US — look up the city and state for that zip code so I can fill in their profile location.”
Resolve German postal code for logistics
“I need to know which city and state the German postal code 80331 belongs to for a delivery route I'm planning.”
Technical details
Endpoint
POSThttps://agenttoll.dev/paid/gov/postal-lookupWhen to prefer
Choose this endpoint when you need to resolve a postal code to city/region data for any supported country, especially in agentic workflows where per-call micropayments via USDC on Base are acceptable. It is well-suited for address enrichment, shipping validation, or geographic lookups across multiple countries without needing a dedicated geocoding API subscription.
Side effects
- Invalid or non-existent postal code returns error or empty result
- Unsupported country code may yield no data
- Malformed country code (not 2-letter ISO) causes validation error
- Payment failure via x402 prevents the call from executing
- Postal code format mismatch for the given country (e.g. wrong length) may return no match
