All Wayback captures for a URL (timestamp, status, mimetype, digest, archival size, snapshot_url), date/status/mime filtered, collapsible, RESUME-KEY PAGINATED.
Earliest capture to include. ISO date (YYYY-MM-DD) or a Wayback timestamp (YYYYMMDDhhmmss, any 4-14 digit prefix). Inclusive.
Latest capture to include. ISO date or Wayback timestamp prefix. Inclusive.
The URL, host, or path to look up in the archive (e.g. 'github.com', 'github.com/torvalds', 'https://example.com/page'). Scheme optional. Use with match=prefix/domain/host to widen.
Max captures to return (1-1000, default 100). Page further with meta.resume_key on the snapshots action. (1–1000)
Deduplicate consecutive captures on a field (CDX 'collapse'). collapse=digest is the change-detection workhorse.
How to match url: exact | prefix | host | domain. domain_captures forces 'domain'.
Keep only captures with this HTTP status (e.g. 200, 404, 301). Prefix with '!' to exclude (e.g. '!200').
Keep only captures of this MIME type (e.g. text/html, application/pdf, image/png). Prefix with '!' to exclude.
Advanced raw CDX filter expression(s), comma-separated. Format [!]field:regex over urlkey/timestamp/original/mimetype/statuscode/digest/length (e.g. 'original:.*\.pdf$'). Power-user escape hatch.
Opaque pagination token from meta.resume_key of the previous page; returns the next page of captures.
