The free API is amazing I have so many little helper bots that help me automated my life. It's easy better easier and more feature rich than twilio or slack. I made my own stock management bot that ate a screener spreadsheet I upload in the chat and tell me if I should sell my stocks.

There is even that freqtrade bot that runs on telegram, even RSS bots. It really is amazing. So easy to use for chat ops.

I don't know what else you would use the API for.
