# Docker Domain Verification Change Watch

> Docker Domain Verification Change Watch is a paid API for AI agents from dns.intel.rallylive.ca, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-20).

Runs Docker domain verification check, compares result against previous call (stored 90 days), and returns current status plus what changed and when.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 docker-domain-verification-change-watch-667084ac
```

Example prompt: Watch for any changes to the Docker domain verification status for acme.com and let me know if anything changes — especially if it gets added, removed, or the verification token shifts.

## When to prefer this

Use this endpoint when you need to detect changes in Docker domain verification over time rather than just the current state. It is purpose-built for monitoring and alerting workflows where you want to know if verification was added, removed, or modified. Prefer this over a plain DNS lookup when you need a before/after diff and change detection without building your own state management.

## Known failure modes

- Domain not found or invalid domain name provided — returns error or empty verification result
- No previous check stored (first call) — changed flag may be false or undefined with no before/after diff
- DNS resolution failure — upstream DoH provider unreachable, returns error
- Rate limiting or payment failure — x402 payment not processed, request rejected

## How this service works

Change watch for has docker 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 Docker domain verification status, a boolean indicating whether it changed since the last check, a diff of which fields changed with before/after values, and a timestamp of when it was last observed. Previous results are retained for 90 days for comparison.
