Spix is the first communications platform built for AI agents, not humans. No dashboard, no drag-and-drop builders, just a single CLI binary that lets any agent make phone calls, send SMS, and send email with one command. What makes it different: - CLI-first: works with OpenClaw, Claude Code, Codex, and any agent framework - Flags-first: zero interactive prompts, fully scriptable - Built-in AI voice calls with STT + TTS + LLM orchestration - Credit-based billing — pay only for what agents use
