## 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 dkim-selector-mailo-watch-5b7c33f5
```

Example prompt: Check if the Mailo DKIM selector DNS record has changed for example.com and tell me what changed, including the before and after values.

## When to prefer this

Choose this endpoint when you specifically need to detect changes in the Mailo DKIM selector DNS record over time, rather than just fetching the current record. It is ideal for automated monitoring workflows, alerting pipelines, or post-deployment verification where knowing what changed (not just what the current value is) is the primary goal. Prefer this over a plain DKIM lookup when historical comparison and change notification are required.

## Known failure modes

- Domain not found or DNS resolution failure returns an error or empty record set
- No previous result stored (first call) results in changed=false or no diff available
- Stale comparison data if more than 90 days have passed since the last check
- Network or upstream DNS resolver unavailability causing timeout
- Invalid or malformed domain input causing request failure

## How this service works

Change watch for dkim selector mailo: 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 DKIM Mailo selector record, a boolean indicating whether it changed since the last call, a list of fields that changed with before/after values, and the timestamp of when the record was last seen. Previous results are retained for 90 days for comparison.
