- `crawler-scraper/arquivo` | qualifies-with-caveat | evidence documented | binding request-rate | category archive
- needs card no, phone no, ID no, institution no | verified 2026-10-30T11:10:03.630Z (live) | stale on 2026-11-30
- url https://arquivo.pt/
- free tier: keyless CDX server, full-text and URL search API, Memento API, image search and replay of the Portuguese web archive, each limited per IP address | unit: requests | metered on: request-count | read on: 2026-10-30 | source: [1]
- per-object cap: not applicable: the unit is a capture | source: [2]
- retention: no expiry stated | source: [2]
- egress: not applicable: the archived body | metered: no | source: [2]
- identity: anonymous | detail: keyless; the limits are counted per IP address
- interface: rest
- limits:
  - request-rate (binding): CDX server and the full-text and URL search API 250 requests a minute per IP address; Memento and image search 400 a minute; replay at /wayback 4,000 a minute [1]
  - request-rate (binding): an IP address over any of these limits is blocked permanently; a 429 answer means slow down [1]
- binding note: 250 CDX requests a minute per IP address, and a permanent block past the limit
- interface detail: CDX server answering JSON lines, the Arquivo.pt API for full-text and URL search, the Memento API, image search, replay at /wayback and /noFrame/replay, and CDXJ index files for bulk access
- tooling: plain HTTP with no key; the CDX server takes output=json and limit parameters
- composes with: It has no closest operation, so it answers only a listing
- reliability: the CDX endpoint answered 200 with a capture row and no key, with x-ratelimit-policy 250;w=60
- notes: It holds far fewer pages than the Wayback Machine but more of the non-English web.
- evidence note: per-IP limits read on the vendor's API page; the CDX endpoint read with no key
