## 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 apexapi-geo-address-validator-cbcf84a6 -d '<json body>'
```

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

## When to prefer this

Use this endpoint when you need to confirm that a physical mailing or shipping address is real and deliverable before storing it, sending mail, or completing a checkout flow — particularly when you want a pay-per-call model with no API key setup. Prefer this over form-level regex validation when actual existence verification matters.

## Known failure modes

- Malformed or empty query string returns a validation error
- Address not found in reference database returns invalid/undeliverable status
- Ambiguous address with multiple matches may return low-confidence result
- Payment failure via x402 results in 402 response before processing
- Service timeout or upstream geo data unavailability causes 5xx error
