## 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 cloudpulsepoint-domain-whois-expiry-checker-167d101e -d '<json body>'
```

Example prompt: Check when the domain registration for https://mybusiness.com expires and tell me how many days I have left before it lapses.

## When to prefer this

Use this endpoint when you specifically need domain registration expiry data from WHOIS — particularly when monitoring renewal deadlines, auditing a portfolio of domains, or setting up alerts before a domain lapses. Prefer this over the combined health-check endpoint when you only need expiry information and want to minimize cost. Choose this over manual WHOIS lookups when automating domain lifecycle monitoring at scale.

## Known failure modes

- Domain not found in WHOIS (unregistered or private registry) — returns error with no expiry data
- Private or loopback URL submitted — rejected with HTTP 400 before payment is charged
- WHOIS rate limiting or registry unavailability causes lookup failure
- Domain uses a registrar with restricted WHOIS access (e.g. privacy-protected), limiting expiry data
- Malformed or non-public URL input returns HTTP 400 validation error

## How this service works

Look up the domain's registration expiry via WHOIS and report the expiry date and days remaining. Use to catch domains about to lapse before they drop and take DNS/email/site down with them.

## Output

Returns the domain's WHOIS-sourced registration expiry date and the number of days remaining until that date, enabling proactive renewal before the domain lapses and causes DNS, email, or site outages.
