Telnyx
Communications API platform built for real-time AI agents.
About
Telnyx is a communications platform that gives developers voice, SMS, WhatsApp, and email through one REST API, positioned as infrastructure for real-time AI agents. Its AI Assistants can hold phone conversations, join meetings as programmable participants with live transcription, and produce summaries, action items, and decisions from calls.
The platform also offers LLM inference, speech-to-text, and text-to-speech, plus an MCP server so agents can drive meetings, transcripts, and artifacts programmatically. A 2026 Email API launch completed its multi-channel story, letting one provider cover every channel an agent needs.
