This website serves pi and interactive demos that you can listen to or see pi with. It does not provide a search function.
Found on http://www.numberworld.org/y-cruncher/faq.html#download_digits, which wisely warns "But this is likely to be temporary."
BBOS provides a command line interface (or CLI) that lets you interface with the RP2040 board directly. This makes it possible to not only interact with the Pi but also handle practical functions like real-time debugging. https://github.com/mcknly/breadboard-os
