answers 402

The archived history of any website from the Internet Archive Wayback Machine: first-seen date, last-seen date, total snapshots, how many distinct versions the page went through, and a timeline of snapshot links (one per month). Great for domain due-diligence, brand history and change tracking. JSON response. $0.02 USDC per call, pay via x402, no API key.

We sent a real GET request to this endpoint and it answered 402 with payment requirements we could parse.
