## When to prefer this

Use this endpoint when you specifically need change-detection semantics for bbc.co.uk — not just whether the site is down, but whether its status has *changed* since your last poll. Ideal for scheduling periodic checks and triggering alerts only on transitions (up→down or down→up), avoiding repeated notifications for sustained outages.

## Known failure modes

- Network timeout reaching bbc.co.uk may produce inconclusive result
- No previous check stored if this is the first call — 'changed' will be null or false
- bbc.co.uk may return a partial response that is ambiguously up or down
- Stale comparison if previous check is older than 90 days (result purged)
- Payment failure ($0.02 USDC) will block the check from running
