web-archive
Yandex (cache / SERP)
The Russian search engine, listed here because it is the last major engine still surfacing cached copies of web pages. There is no stable API: you run an ordinary search on yandex.com and look for the 'saved copy' link beside a result. Worth a try when a page disappeared too recently for the web archives to have caught it. Expect anti-bot checks — the site frequently challenges visitors before showing results.

No programmatic check — opens the archive’s own search.
Why it’s useful & how it works
JS/anti-bot challenge ('checking your browser') both ways — even datacenter proxies hit it. Residential + brittle. Link-only (hand a SERP link).
What’s inside
Search-index-backed.
