Is that link actually alive?
A status check says 200 OK and moves on. We catch the links that lie — gone, moved, parked, out of stock — and hand back a verdict with the receipts.

How it works
01
Fetch like a browser
We render the page — JavaScript and all — so soft-404s that only appear after scripts run get caught too.
02
Classify on many signals
HTTP status, title and canonical heuristics, content drift — escalating to an LLM only on the genuinely ambiguous cases.
03
Fail open, always
We call a link dead only when confident. Unreachable is never dead. /heal returns a replacement only when it clears the bar.
A key and a URL. That's the whole integration.
Every call ships an evidence trace you can audit and reproduce. Pay only for checks that return a verdict.
