# DNS TXT via AliDNS Change Watch

> DNS TXT via AliDNS 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 2026-10-21).

Monitors DNS TXT records for a domain via AliDNS (DNS over HTTPS), comparing current results against a stored baseline and returning a changed flag plus before/after diff.

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-txt-via-alidns-change-watch-858617d1
```

Example prompt: Keep an eye on the DNS TXT records for example.com using AliDNS and tell me if anything has changed since the last time you checked — show me exactly what fields changed and what the old vs. new values are.

## When to prefer this

Use this endpoint when you specifically want to monitor DNS TXT records as resolved by AliDNS (Alibaba's public DNS), which is useful for tracking how Chinese or Asia-Pacific resolvers see your domain. Prefer this over generic DNS TXT lookups when you need change detection with a stored diff rather than just a point-in-time lookup. Ideal for scheduling periodic checks and triggering alerts on changes.

## Known failure modes

- Domain not yet seen before — no baseline exists so 'changed' may be indeterminate on first call
- AliDNS resolution failure or timeout returns an error with no record data
- Invalid or malformed domain name returns a validation error
- NXDOMAIN (domain does not exist) returns empty records and a NXDOMAIN response code
- Baseline expired after 90 days — comparison resets to a fresh baseline

## How this service works

Change watch for dns txt via alidns: 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 DNS TXT records for the domain as seen by AliDNS, a boolean 'changed' flag, a list of fields that changed with their before and after values, and a timestamp of when the record was last seen. The previous result is retained for 90 days for comparison.
