**APIs profiled:** 5

Layercode provides voice-AI agent infrastructure - low-latency voice pipelines that turn any LLM or text-based agent into a conversational voice agent for web, mobile, and phone. A REST API manages agents, sessions, and outbound calls, while a realtime WebSocket transport streams audio to the browser and a signed webhook delivers transcripts to your backend, which streams text-to-speech responses back over Server-Sent Events.
