## Internet Archive Wayback Machine

- `crawler-scraper/wayback` | qualifies | evidence measured | binding per-object-cap | category archive
- needs card no, phone no, ID no, institution no | verified 2026-10-22 (live) | stale on 2026-12-22
- url https://web.archive.org/
- free tier: keyless listing, closest and replay of existing captures; Save Page Now needs keys | unit: requests | metered on: request-count | read on: 2026-10-22 | source: [1]
- per-object cap: not applicable: the unit is a capture | source: [1]
- retention: captures are held indefinitely; a listing row's record_length is the compressed WARC size, not the body | source: [1]
- egress: served; a direct replay of a large object is not measured here | metered: no | source: [1]
- identity: anonymous | detail: listing, closest and replay need nothing; Save Page Now needs Internet Archive API keys
- interface: rest
- limits:
  - request-rate: Save Page Now is held after 5 saves of one URL a day on this deployment; the listing and replay are keyless
  - per-object-cap (binding): a listing pages by a CDX resume key; a page that holds limit captures names a cursor for the next
- interface detail: CDX server, Availability API and raw replay with an id_ suffix
- tooling: not stated
- composes with: Rung four of the escalation ladder; the copy that survives the origin changing, as hostloc.com did
- notes: The single most useful service in this topic and the only one that answered within 4 s on every call. A short at= is the start of its period, so at=2024-06 asks 20240601000000.
