Introduction

The Bolcho API lets you build voice AI products programmatically — create assistants, connect phone numbers over SIP, place and receive calls, attach knowledge and tools, and stream transcripts and analytics. Everything in the dashboard is available over a REST API.

All endpoints are versioned under /v1.

What you can build

• Outbound campaigns — provision a SIP trunk + numbers, then place calls that connect a caller to an AI assistant.
• Inbound IVR / support lines — route incoming numbers to assistants with knowledge bases and tools.
• In-app voice / web calls — start a browser call and join with the returned LiveKit token.
• Back-office automation — read call transcripts, recordings, structured outputs, and analytics.

Conventions: requests and responses are JSON. Timestamps are ISO-8601. IDs are UUIDs (or prefixed handles like ST_… for LiveKit SIP resources). List endpoints accept ?limit= and ?offset=.
