## 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 nexusapi-geo-address-validation-74c1e0e7 -d '<json body>'
```

Example prompt: Can you check whether '1600 Pennsylvania Avenue NW, Washington DC 20500' is a valid, real deliverable address?

## When to prefer this

Use this endpoint when you need to verify that a user-submitted or programmatically generated address actually exists and is correctly formatted, especially before storing addresses in a database, shipping a package, or sending mail. Prefer this over geocoding-only endpoints when your primary need is validation rather than coordinate lookup.

## Known failure modes

- Address string is ambiguous or incomplete — returns invalid or low-confidence result
- Malformed query input — returns 400 or error object
- Address not found in reference database — returns not-found or invalid status
- Service unavailable or payment not processed — returns 402 or 5xx error
