How this service works
Look up a URL in the Internet Archive's Wayback Machine: returns the archived snapshot closest to an optional timestamp (default: most recent), with the snapshot URL, capture time, and archived HTTP status. Useful for citations, dead-link recovery, and checking what a page said at a point in time. URLs never archived return {available:false}.
Output
Returns the archived snapshot URL on the Wayback Machine, the exact capture timestamp, and the HTTP status code that was recorded at the time of archiving.
Example use cases
Example prompt
“Can you find the archived version of https://www.example.com/old-article closest to January 2020 in the Wayback Machine? I need the snapshot URL and when it was captured.”
Technical details
Endpoint
POSThttps://agent402.tools/api/archive-snapshotWhen to prefer
Use this endpoint when you need to retrieve historical snapshots of a webpage from the Internet Archive, recover dead or deleted links, find citations for content that has since changed or disappeared, or verify what a URL contained at a specific point in time. Prefer this over generic web scraping when the live URL is no longer accessible or when historical accuracy is required.
Side effects
- URL has never been crawled by the Wayback Machine — returns no snapshot found
- Malformed or missing URL parameter — returns validation error
- Timestamp format incorrect (not 4-14 digits) — returns parsing error
- Wayback Machine API unavailable — returns upstream service error
- URL exists in archive but no snapshot near the requested timestamp
