## 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-validator-a328d3a8 -d '<json body>'
```

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

## When to prefer this

Use this endpoint when you need to confirm that a user-supplied or data-sourced address is real, deliverable, and properly formatted before storing, shipping, or displaying it. Prefer it over geocoding endpoints when the goal is validation and data quality rather than coordinate lookup. Ideal for e-commerce checkout flows, CRM data hygiene, and lead qualification pipelines.

## Known failure modes

- Malformed or empty address string returns a validation error
- Non-existent or fictitious addresses return invalid/undeliverable status
- Ambiguous addresses (missing city or postal code) may return low-confidence or failed validation
