```sh
zero fetch --capability penny-data-uk-postcode-lookup-b7bd189a
```

Example prompt: What ward, region, and constituency does the postcode SW1A 1AA fall under, and can you give me its exact latitude and longitude?

## When to prefer this

Choose this endpoint when you need quick, structured geographic and administrative data for a UK postcode — especially ward, constituency, district, and coordinates — without wanting to set up an API key or account. It is ideal for pay-per-call agent workflows where you only look up postcodes occasionally and want to pay micro-amounts in USDC on Base via x402.

## Known failure modes

- Invalid or malformed postcode returns an error or empty result
- Postcode not found in database returns a 404 or null response
- Missing payment or insufficient USDC balance causes a 402 Payment Required response
- Network timeout on the Vercel-hosted endpoint
