## 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-cname-change-watch-via-alidns-c8c34082
```

Example prompt: Watch the CNAME records for example.com via AliDNS and tell me if anything has changed since the last check — show me the before and after values if it did.

## When to prefer this

Choose this endpoint when you specifically want to detect changes in CNAME records as seen from AliDNS (223.5.5.5), particularly for monitoring domains popular in Asian markets or for cross-resolver comparison. Prefer this over a plain CNAME lookup when your goal is drift detection, alerting, or auditing record changes over time rather than just resolving the current value.

## Known failure modes

- Domain not found or NXDOMAIN — CNAME records absent, no diff possible
- No previous check stored — first call returns current state with changed=false or null baseline
- AliDNS resolver unreachable — upstream DNS failure
- Invalid domain input — malformed domain name returns error
- Previous result expired (older than 90 days) — treated as first call

## How this service works

Change watch for dns cname 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 CNAME records as resolved by AliDNS, a boolean 'changed' flag indicating whether the result differs from the previous call for the same domain, a list of fields that changed with their before and after values, and a timestamp of when the record was last seen. Previous results are retained for 90 days.
