AgentCall
Phone numbers for AI agents: voice, SMS, OTP & memory
The phone number API for AI agents: US and Canada numbers, SMS, OTP extraction, AI voice, and cross-call memory. REST API plus MCP server. Free tier.
Hey Product Hunt! 👋
I built AgentCall because every AI agent I worked with eventually hit the same wall: it needed a real phone number. SMS verification, 2FA/OTP codes, voice calls, a number people could actually reach — and wiring that up through traditional telecom APIs like Twilio was painful and not built for agents.
AgentCall is the phone number API designed for AI agents:
• Provision real US/Canada numbers in seconds via REST API or MCP
• Send/receive SMS and auto-extract OTP codes
• AI voice calls (inbound + outbound) in 13 languages, with full transcripts
• Cross-call memory — your agent remembers past callers and picks up the thread
• Works inside Claude, Cursor, Windsurf, Hermes, and OpenClaw via our hosted MCP server
There's a free tier (no card required) so you can try it right away. Would love your feedback — happy to answer any questions in the comments!
