Quick Example

Create a voice agent and make a call in two API requests:

1 import requests
2 
3 API_KEY = "lev_YOUR_API_KEY"
4 BASE = "https://api.levrage.ai/v1"
5 headers = {"Authorization": f"Bearer {API_KEY}", "Content-Type": "application/json"}
6 
7 # 1. Create an agent
8 agent = requests.post(f"{BASE}/agents", headers=headers, json={
9     "name": "My Sales Agent",
10     "agent_type": "sales",
11     "language": "English",
12     "voice": "female",
13     "start_flow": "Hello! I am calling from Acme Corp. Am I speaking with the right person?",
14     "end_flow": "Thank you for your time. Have a great day!"
15 }).json()
16 
17 agent_id = agent["data"]["id"]
18 
19 # 2. Make a call
20 call = requests.post(f"{BASE}/call", headers=headers, json={
21     "agent_id": agent_id,
22     "source_number": "+919240018601",
23     "phone_number": "+919876543210"
24 }).json()
25 
26 print(f"Call initiated: {call['data']['id']}")

Response Format

All responses follow a consistent envelope:

1 {
2   "success": true,
3   "data": { ... },
4   "request_id": "req_abc123",
5   "timestamp": "2025-01-01T12:00:00Z"
6 }

Error responses:

1 {
2   "success": false,
3   "error": {
4     "code": "validation_error",
5     "message": "Agent name is already in use"
6   },
7   "request_id": "req_abc123",
8   "timestamp": "2025-01-01T12:00:00Z"
9 }
