LINQ CLI – iMessage API for Developers

A command-line tool that gives free access to send/receive iMessages, RCS, and SMS via an API. Useful for developers building conversational AI, bots, and automation. Solves the lack of easy iMessage programmatic access.

Apple's lock on iMessage has frustrated developers for years, and with conversational AI tooling exploding right now, demand for native iMessage programmability is real and growing fast. No clear incumbent exists in this exact space — Twilio owns SMS/RCS but has no iMessage access, which is the entire wedge here. The $2k–10k/mo revenue band is plausible for a niche devtool with usage-based pricing, but the ceiling is low unless enterprise adoption materializes. The single most likely failure mode is Apple — any enforcement action, OS update, or policy change that breaks the underlying method (almost certainly a Mac-relay or private API approach) kills the product overnight with no recourse.
