## When to prefer this

Use this endpoint when you need change-aware uptime monitoring for autotrader.ca specifically — it not only reports current status but compares it to the last known state, making it ideal for scheduling periodic checks and triggering alerts only on state transitions rather than on every poll.

## Known failure modes

- No previous check stored (first call returns no diff data)
- autotrader.ca returns ambiguous HTTP response making up/down determination uncertain
- Network timeout reaching autotrader.ca causing inconclusive result
- Payment failure ($0.02 USDC) preventing the check from running
- Stale stored result if 90-day retention window has expired

Schedule it to be alerted when this changes. $0.02 per check.

## Output

Previous result is retained for 90 days for comparison.
