Example use cases
Recover deleted webpage content
“The page at https://techcrunch.com/2019/05/10/startup-funding-round got taken down — can you check if the Wayback Machine archived it and give me the closest snapshot so I can read it?”
Verify historical existence of a URL
“I need to confirm that https://www.oldcompany.com/press-release-2018 actually existed at some point — can you check the Wayback Machine for an archived version?”
Research original version of a changed page
“Can you look up whether https://en.wikipedia.org/wiki/Quantum_computing was archived by the Wayback Machine? I want to see the closest historical snapshot they have.”
Technical details
Endpoint
GEThttps://api.molcloud.net/api/web/wayback?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to check whether a specific URL has been captured by the Internet Archive's Wayback Machine, particularly for recovering deleted content, verifying historical existence of pages, or accessing older versions of webpages. Prefer this over general web scraping tools when the goal is specifically to access archived historical versions rather than the live current page.
Side effects
- URL not found in Wayback Machine returns archived: false with no snapshot URL
- Invalid or malformed target URL causes a request error
- Wayback Machine API unavailability results in a timeout or error response
- Missing required 'url' query parameter returns a validation error
