## 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 agentrxi-address-verification-standardization-5a472cef
```

Example prompt: Can you verify the address '221B Baker Street, London, NW1 6XE' and tell me if it's valid, what the parsed components are, and its coordinates?

## When to prefer this

Choose this endpoint when you need address validation with structured parsed output, geocoordinates, timezone, and a confidence verdict in a single call — especially for international addresses. Ideal for pre-shipping validation, CRM data cleansing, or any workflow where address accuracy and structured components matter more than just a geocode.

## Known failure modes

- Address not found or unrecognizable — low confidence or null result returned
- Ambiguous input yields multiple alternatives rather than a single verified result
- Missing required 'address' query parameter causes a 400 error
- Unsupported or malformed country code may restrict results incorrectly
- Very new or rural addresses may not be in the reference dataset

## How this service works

Address verification and standardization worldwide: parsed components (house number, street, city, state, postcode, country), confidence to building, street or city level, a plain verdict, coordinates, timezone and alternatives.

## Output

Returns parsed address components (house number, street, city, state, postcode, country), a confidence level (building, street, or city), a plain verdict on address validity, geographic coordinates (lat/lng), timezone, and a list of address alternatives when the input is ambiguous.
