Is this allowed under Apple's ToS?

I recall the Beeper Mini debacle not so long ago, and fear that this may be a house built on sand.

Apple is not necessarily against programmatic messaging. In fact, they actually developed Applescript for people to do so. Beeper was using it to replace the iMessage interface when it already exists, which is why I think Apple was against it. We're doing something fundamentally different - allowing agents to interact with humans on iMessage, which is something that the current iMessage interface cannot do.

Apple were against Beeper because it opened their platform to people who weren’t Apple-sanctioned users.

Apple might have cited a different technical reason but that would only have been to avoid antitrust regulations.

Unfortunately for you, this startup idea also allows non-sanctioned entities access to iMessage. So Apple will ban your access to.
