GET /api/wayback-snapshot

unprobed

Finds the closest archived snapshot of any public URL in the Internet Archive Wayback Machine. Returns the snapshot URL, capture timestamp and original HTTP status. Optional timestamp (YYYYMMDD or longer) targets a specific date. For research agents verifying past content, checking link rot, or citing sources as they appeared.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
