How this service works
Internet Archive lookup: whether a snapshot of a URL exists and its closest capture to a given date — read pages that are now dead
Output
Returns a JSON object with a boolean availability flag, the snapshot timestamp (e.g. '20200101000000'), the original URL, and a full Wayback Machine snapshot URL pointing to archive.org if an archived version exists.
Example use cases
Verify deleted crypto project website snapshot
“I need to check if that sketchy DeFi project's website that went down last month has an archived version on the Wayback Machine so I can review what they promised versus what happened.”
Find historical version of smart contract docs
“Can you look up the archived snapshot of that contract's GitHub documentation page from before the audit? I want to compare the original spec with the current version.”
Confirm NFT marketplace listing history
“Check the Wayback Machine for an archived copy of that NFT collection's original listing page so I can verify the initial mint details and original metadata.”
Technical details
Endpoint
POSThttps://eltociear-tokenguard.hf.space/data/waybackWhen to prefer
Use this endpoint when you need to verify whether a specific URL has been archived by the Internet Archive's Wayback Machine and retrieve the snapshot link, especially for checking deleted or changed pages. Prefer this over direct Wayback Machine API calls when you need a pay-per-call micropayment model via x402 on Base.
Side effects
- URL has never been crawled by the Wayback Machine — returns available: false with no snapshot_url
- Malformed or missing URL input — returns 4xx error
- Wayback Machine API is temporarily unavailable — service timeout or 5xx error
- URL is in an exclusion list (robots.txt blocked) — may return unavailable even if archived
