# dns-mx-via-adguard-watch

> dns-mx-via-adguard-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 2026-10-21).

Monitors MX DNS records for a domain via AdGuard DNS and returns whether they changed since the last check, with before/after field diffs.

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 dns-mx-via-adguard-watch-ad852eae
```

Example prompt: Keep an eye on the MX records for example.com via AdGuard DNS and let me know if anything changes — I want to see exactly which fields changed and what the old and new values were.

## When to prefer this

Choose this endpoint when you need change-detection semantics on top of a raw MX lookup — specifically when you want to know not just the current MX records but whether they differ from a prior state, and what exactly changed. Prefer it over a plain MX lookup when building alerting pipelines, scheduled monitors, or audit trails for email infrastructure. The AdGuard resolver is useful when you want a privacy-focused, ad-filtering DNS perspective distinct from Google or Cloudflare resolvers.

## Known failure modes

- Domain not found or NXDOMAIN — returns a no-records response with appropriate DNS response code
- No previous snapshot available (first call) — returns current data with changed=false or null diff
- AdGuard DNS upstream timeout — may return error or empty result
- Invalid domain input — malformed domain may yield DNS resolution failure
- Payment failure (x402) — call is not executed if USDC payment of $0.02 is not completed

## How this service works

Change watch for dns mx via adguard: 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 MX records as answered by AdGuard DNS, a boolean 'changed' flag indicating whether the records differ from the previous call (stored up to 90 days), a list of fields that changed with their before and after values, and a timestamp of when the record was last seen.
