## When to prefer this

Use this endpoint when you need change-detection semantics — not just a live status snapshot but a comparison against the previous known state for walmart.com specifically. Ideal for scheduling periodic polls and triggering alerts only when something actually changes, avoiding redundant notifications during stable outages or uptime periods.

## Known failure modes

- Previous result not found if first call or 90-day history expired — no diff available
- Network error reaching walmart.com from edge — may return error status instead of up/down
- Payment failure for $0.02 USDC charge — request rejected before check runs
- Rate limiting or API gateway errors if called too frequently
