Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```

Example prompt: Keep an eye on whether example.com's SPF record authorizes Mailjet as a sender, and let me know if anything changes compared to last time you checked.

## When to prefer this

Choose this endpoint when you need to be alerted to changes in a domain's SPF authorization of Mailjet over time, rather than just checking the current state once. It is ideal for scheduled monitoring workflows, compliance audits, or competitive intelligence where detecting the transition — not just the current value — matters. Prefer it over a one-shot SPF check when you want before/after change context automatically maintained.

## Known failure modes

- Domain does not exist or has no SPF record — returns current answer reflecting absence of authorization
- First-ever check for domain returns no comparison data since no prior result is stored
- DNS lookup timeout or failure — check may error without a result
- Result history older than 90 days is discarded — comparison unavailable
- Invalid or missing domain parameter — request rejected

## How this service works

Change watch for spf authorizes 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 SPF-authorizes-Mailjet status for the domain, a boolean 'changed' flag indicating whether the result differs from the previous check (stored up to 90 days), the specific fields that changed with their before and after values, and the timestamp of when the result was last observed.
