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!
