I use a signal api on a daily basis for all my agentic chatting and notifications about energy prices and server downtime notification.

Setup was quick enough but it needs a real phone number once during setup which is kind of a hassle. still better than using telegram which has no encryption for the bot backend so the devs can read everything you write

I run my agent over Signal with this, the only difference with Telegram is you need to host this. Other than that, it's great.

I wish WhatsApp did... hopefully it goes the way of BBM and a more developer friendly platform becomes the norm among normies.

Same. I used to use telegram for everything and then stopped after I realised it wasn’t really and to end encrypted. The bots were super useful. I used to have one I could ask different bus times for. Was so much better than the app the local bus company had made.

Not having a bot API is one of the many things that makes Signal amazing
