## 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-mailjet-change-watch-30b1ea3d
```

Example prompt: Keep an eye on the Mailjet DKIM selector for example.com and let me know if it changes from what it was last time — I need to catch any unexpected modifications to our email authentication setup.

## When to prefer this

Use this endpoint when you need to detect changes to a domain's Mailjet DKIM DNS record over time rather than just retrieving the current value. It is ideal for scheduled monitoring workflows, compliance audits, or alerting pipelines where knowing whether the record changed (and what exactly changed) is more valuable than a raw lookup. Prefer this over a plain DKIM lookup when you have a persistent monitoring need tied to Mailjet specifically.

## Known failure modes

- Domain not previously checked — no baseline to compare against (first call returns current value only)
- Domain does not exist or has no mailjet DKIM record — returns empty or NXDOMAIN result
- Baseline expired after 90 days — comparison not possible
- Invalid domain input — request error
- Payment not processed — x402 payment required before response

## How this service works

Change watch for dkim selector mailjet: 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 selector record value for the mailjet selector, a boolean 'changed' flag indicating whether it differs from the previous check (stored up to 90 days), a list of fields that changed with before and after values, and a timestamp of when the record was last seen.
