Introduction

Jelliu runs AI agents that talk to your customers: they place and answer phone calls, reply on WhatsApp, handle email, and chat on your website through an embeddable web chat widget. The Jelliu API gives your own systems programmatic access to the same workspace you manage in the dashboard.

With the API you can:

• Manage agents — list, create and update the voice and chat agents in your workspace.
• Run campaigns — create outreach campaigns on the voice, whatsapp, webchat or email channel, load contacts, and activate or pause them.
• Work with contacts — add contacts one by one or in bulk, and read your workspace-wide contact list.
• Read calls and conversations — outcomes, summaries and transcripts after each interaction.
• Pull analytics — the KPIs your dashboard shows.
• React to events — receive signed webhooks when a call ends or a campaign completes.
• Connect AI assistants — expose your workspace to Claude, ChatGPT or Cursor through the MCP server.

Base URLs

Every REST endpoint lives under the /api prefix, for example https://api.jelliu.co/api/agents. Requests and responses are JSON. Successful responses wrap their payload in a data field:

{
  "data": { "...": "..." }
}
