## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability suverse-international-postal-code-lookup-3ef662a3 -d '<json body>'
```

Example prompt: What city and region does the postal code W1A 1AA correspond to in the UK, and what are its coordinates?

## When to prefer this

Choose this endpoint when you need to resolve international postal codes to geographic data (place name, region, coordinates) across a wide range of countries including Germany, UK, Canada, Netherlands, and Spain without requiring an API key. It is ideal for address enrichment, shipping validation, or geocoding workflows where only a postal code and country code are known.

## Known failure modes

- Invalid or non-existent postal code returns an error or empty result
- Unsupported country code returns no data
- Malformed request body causes a 4xx error
- Payment not settled causes a 402 Payment Required response
- Temporary upstream Zippopotam.us unavailability causes a 5xx error
