Arquivo.pt supports Memento Protocol natively, because it uses pywb for the replay of the archived Webpages.

"Memento API helps you find and view versions of web pages that existed at some time in the past"

Arquivo.pt provides the following Memento endpoints:

• TimeGate: https://arquivo.pt/wayback/<url>
• TimeMap: https://arquivo.pt/wayback/timemap/<type>/<url>

The type parameter can be any of the following:

• link – returns an application/link-format as required by the Memento specification.
• cdxj – returns a timemap in the native CDXJ format.
• json – returns the timemap as newline-delimited JSON lines (NDJSON) format.

Memento API only allows URL Search. For more informations visit:
