“For the postcode BS1 4DJ in Bristol, what region and country does it belong to?”
Technical details
Endpoint
GEThttps://anibalb.duckdns.org/x402/uk-postcode?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need lightweight, pay-per-call UK postcode geocoding and administrative data without requiring an API key or account. Ideal for agents that handle sporadic lookups and want to pay in USDC via x402 rather than managing subscription credentials.
Side effects
- Invalid or non-existent postcode returns an error or empty result
- Postcode not found in database (e.g. recently assigned or terminated postcodes)
- Payment failure via x402 prevents access to the response
- Rate limiting or network timeout on the duckdns host
