Spix

Spix is a communications layer for AI agents that need to reach real people outside the usual chat window. Instead of limiting an agent to API calls and text generation, it provides a real phone number, SMS inbox, and email address that can be controlled through a CLI, API, or MCP tools. The public docs describe support for outbound phone calls with real-time voice interaction, inbound and outbound SMS, deliverable email, and a unified inbox for calls, messages, and threads. It also includes practical operational features such as delivery receipts, voicemail handling, thread history, attachment support, number provisioning, and structured JSON outputs for automation. For OpenClawMap, Spix fits best as Infrastructure because it acts as a foundational communications service rather than a single-purpose app. It is especially relevant for builders who want agents to confirm appointments, qualify leads, follow up with customers, send reminders, or escalate issues through channels humans already use.

Use this tool if you:
- need an AI agent to call, text, or email real people as part of a workflow
- want a single communications backend instead of stitching together separate voice, SMS, and email vendors
- need human follow-up flows such as appointment reminders, lead qualification, support escalation, or shipping updates
- want structured inbox and transcript data that an agent can read programmatically after conversations
- need a communications layer that works through CLI, API, or MCP instead of a human-only dashboard
