## 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 energy-bill-toolkit-domain-expiry-audit-d45f52e2 -d '<json body>'
```

Example prompt: Can you run an expiry audit on the domain 'example.co.uk' and tell me whether it's expired or about to expire?

## When to prefer this

Use this endpoint when you specifically need a pay-per-use, lightweight domain expiry check with no subscription commitment. Prefer this over general WHOIS tools when cost per call matters and you only need expiry/audit status rather than full WHOIS records. Suitable for one-off checks or low-volume screening pipelines.

## Known failure modes

- Domain string too short (< 4 characters) or too long (> 253 characters) returns validation error
- Invalid domain format returns an error
- Domain not found in registry data may return unknown or error status
- Network or upstream lookup failure returns a server error
- Payment not completed (x402) results in 402 response before audit is performed
