What is Twilio?

Programmable SMS, voice, and video communication APIs for agent integration.

Twilio is the dominant programmable communications platform, providing APIs for SMS, voice calls, video, WhatsApp messaging, and email that developers integrate into applications. For AI agent builders, Twilio is the most common way to give agents the ability to communicate with humans via phone calls and text messages.

Twilio's SMS API is straightforward — send a message with a POST request including a 'to' number, 'from' number, and message body. Receiving messages works via webhooks: Twilio hits your endpoint when a message arrives, and your application responds with TwiML (Twilio's XML-based markup) or a simple API call. This webhook pattern integrates naturally with agent architectures — the incoming webhook triggers the agent, and the agent's response is sent back via API.
