Ello provides REST endpoints, webhooks, and an MCP server for deep integrations. Below are example calls to get you started.

​
Authentication

All requests require an API key via the Authorization header: Authorization: Bearer <API_KEY>.

​
Create Agent

POST /v1/agents
Authorization: Bearer $ELLO_API_KEY
Content-Type: application/json

{
  "name": "support-agent",
  "language": "en-US",
  "template": "support-basic"
}

​
Deploy Agent

POST /v1/agents/{agent_id}/deploy
Authorization: Bearer $ELLO_API_KEY

Response: { "status":"deploying","deploy_id":"..." }
/

​
Webhook

Subscribe to events such as call.started, call.ended, agent.evolution via your webhook endpoint.

​
Realtime (MCP Server)

Use the MCP server for streaming call-level events and low-latency control. Contact support for SDKs and setup instructions.
Example : simple curl to create an agent (mocked endpoint)
curl -X POST "https://api.ello.ai/v1/agents"   -H "Authorization: Bearer $ELLO_API_KEY"   -H "Content-Type: application/json"
