I think there are still "read-only" clients. I haven't looked in awhile, but I know there were some available via F-Droid (alternative app store) long after the API was cut off. I assume they use standard web scraping for grabbing content.

Also, I'm not sure if it still works, but I think you can still use open source clients that rely on the API, you just have to compile/build them yourself using your account's own personal API key.

I haven't looked into either of these in a while and definitely not an expert on the topic, but I'm sure if you're interested there's enough info out there to find a solution that works for you.
