- The service lists carrier registration, STOP/HELP handling, 320-character message splitting, and hashed sender IDs among its operating details.
Field notes
The setup flow accepts several kinds of inputs: a URL, webhook, OpenAI Prompt ID, Anthropic key, or a description of an agent. The page says a test reply must pass before a line goes live, and describes per-person threads, sender IDs, rate limits, and daily and monthly caps. Its two sample lines use different destinations: one offers a tarot-card exchange, while the other demonstrates filing an SF 311 request.
