## 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 citiview-address-verification-standardization-c20916fd
```

Example prompt: Can you verify this address and tell me if it's real — '221B Baker Street, London, NW1 6XE' — and give me the parsed components, coordinates, and confidence level?

## When to prefer this

Choose this endpoint when you need worldwide address verification with parsed components, geocoordinates, timezone, and confidence scoring in a single call — especially useful for validating user-submitted addresses before shipping, storing, or routing. Prefer over pure geocoding APIs when you also need structured parsing, confidence levels, and alternative suggestions together.

## Known failure modes

- Unrecognizable or completely fictitious address returns low confidence or no results
- Missing required 'address' query parameter returns a 400 error
- Ambiguous addresses may return multiple alternatives with lower confidence rather than a single definitive result
- Very rural or newly built addresses may only resolve to street or city level confidence
- Invalid 2-letter country code may cause filtering to fail or return unexpected results

## 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 level), a plain verdict on address validity, geographic coordinates (lat/lng), timezone, and a list of alternative address suggestions if applicable.
