I was going to mention virtualenv as well, but I have to admit that I find it weird and scary, especially since I haven't found good documentation for it. If there is somebody who is familiar with virtualenv that would probably be the best solution.

Yes, I understand.

What usage patterns do we have to expect? Do we want to hit onionoo to check if the cache is still valid for every request, or should we do "hard caching" for several minutes? The best UX solution would be to have a background task that keeps the cache current so user requests can be delivered without hitting onionoo at all.
In other words, unless we do something intelligent with the cache, the cache is not actually going to be very useful.

Will do.
