## 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 bing-domain-verification-change-watch-9195a4c0
```

Example prompt: Keep an eye on whether example.com has a Bing domain-verification TXT record and let me know the moment it appears, disappears, or changes.

## When to prefer this

Choose this endpoint when you need to be alerted to changes in a domain's Bing verification TXT record over time, rather than just a one-shot lookup. It is ideal for scheduled monitoring workflows where you want diff tracking (before/after values) and change detection rather than just the current state. Prefer it over a plain has-bing-domain-verification check when historical comparison and alerting are required.

## Known failure modes

- Domain not resolvable or invalid — DNS lookup fails
- No previous result stored — first call returns no diff data
- Cloudflare DoH timeout — transient DNS resolution failure
- Malformed domain input — request rejected
- Rate limiting or payment failure — call not processed

## How this service works

Change watch for has bing domain verification: runs the check, compares it with the result from your previous call for the same domain (kept 90 days) and returns the current answer, changed true/false, the fields that changed with before/after values, and when it was last seen. Schedule it to be alerted when this changes. $0.02 per check.

## Output

Returns the current Bing domain-verification status (present/absent), a boolean 'changed' flag indicating whether it differs from the previous call, the specific fields that changed with before and after values, and a timestamp of when it was last observed. History is retained for 90 days per domain.
