How this service works
Website History (Internet Archive). Website history from the Internet Archive: first and last snapshot, years archived, distinct versions per year and the most recent content changes with archive links. Answers what changed on a website and how long it has existed.
Output
A JSON object containing: the queried URL, a boolean indicating if it has ever been archived, the first_seen and last_seen snapshot objects (with dates and archive URLs), a history object broken down by year showing distinct version counts, and the most recent content changes with direct Internet Archive links.
Example use cases
Verifying startup founding date claims
“Can you check when notion.so first appeared in the Internet Archive? A founder claims they launched in 2016 and I want to verify that against the Wayback Machine history.”
Competitive intelligence on website changes
“Pull the Internet Archive history for salesforce.com/pricing — I want to see how many times the pricing page has changed recently and get links to the archived snapshots so I can compare them.”
Due diligence on an acquisition target
“We're evaluating acquiring a company and I need to know how long their site, acmecorp.com, has been online and how actively it's been updated — can you get me the full archive history with first seen date, last seen, and versions per year?”
