Common Crawl index lookup for a URL — alternate/broader coverage with richer fields (detected language, encoding, WARC offset/filename). Cross-source corroboration.

Working example
Parameters

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.

Common Crawl index id (e.g. 'CC-MAIN-2026-21'). Omit to use the newest index. List ids via action='cc_indexes'.

URL match mode for the Common Crawl index query.

Max captures to return (1-1000, default 100). Page further with meta.resume_key on the snapshots action. (1–1000)

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.
