Example prompt: Keep an eye on whether example.com's SPF record authorizes Proton Mail and let me know if it changes — compare against the last check and tell me what changed and when.

## When to prefer this

Use this endpoint when you need to detect changes in SPF authorization for Proton Mail over time rather than just the current state. It is ideal for scheduled monitoring workflows, alerting pipelines, or compliance checks where you need to know not just the current value but whether it changed and exactly what changed since the last check. Prefer this over a simple point-in-time SPF check when tracking email infrastructure migrations, auditing SPF policy changes, or watching for unauthorized Proton Mail configuration additions.

## Known failure modes

- Domain not found or invalid domain name provided
- No previous check stored (first call returns no comparison data)
- DNS lookup failure preventing SPF record retrieval
- Previous check data expired (older than 90 days, comparison unavailable)
- Rate limiting or payment failure preventing the check

## How this service works

Change watch for spf authorizes proton: 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 boolean result of whether the domain's SPF record authorizes Proton Mail, a 'changed' true/false flag comparing against the previous check (retained for 90 days), the specific fields that changed with their before and after values, and a timestamp of when the state was last observed.
