## 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 dt0ur-online-zip-postal-code-to-geolocation-resolver-203c7dbc -d '<json body>'
```

Example prompt: What are the latitude and longitude coordinates for US ZIP code 10001, and which state and county does it fall in?

## When to prefer this

Use this endpoint when you need to geocode a postal or ZIP code — particularly when you need both coordinates and administrative jurisdiction data (state, county, municipality) in a single call. Prefer it over full address geocoding when only a ZIP/postal code is available. It supports international postal codes beyond US ZIP codes, making it suitable for global use cases.

## Known failure modes

- Invalid or nonexistent ZIP/postal code returns an error or empty result
- Unsupported country code may result in no data or an error response
- Malformed country code (not ISO 2-letter) may cause a validation error
- Network timeout or service unavailability returns a 5xx error
