Wayback Machine Toolkit — Archived URLs, Snapshots & Diffs

actor-start

Charged once per run, and only after the first paid row — an index row, archived page or diff report — has been delivered. A run that returns nothing is not charged at all.

snapshot-index-row

One archived capture listed from the Wayback Machine's CDX index: timestamp, archived HTTP status, MIME type, content digest, size and a working Wayback link. By default the index collapses captures whose content did not change, so an unchanged page costs one row rather than one per crawl.

diff-report

One comparison of a page between two archived dates: added and removed lines, word counts, a similarity ratio, the headings that appeared or vanished, the prices that changed, and a plain-English summary. Fetching and parsing both captures is included in this price.
