Headless voice sessions

Open an AI voice session with an agent from your own app:

s = client.voice_sessions.create("agent_abc123")
# s = {"token": ..., "url": "wss://livekit.call2me.app", "room_name": ..., "session_limit_sec": 3600}
# Connect a LiveKit client with s["token"] + s["url"]; the agent auto-joins and talks.

Chats

client.chats.list(limit=50)
client.chats.get("session_id")
client.chats.send_message("session_id", "Hello!", model="openrouter/auto")

Events

Forward application errors and business events to the Call2Me observability pipeline. The POST endpoint is public; sending the API key lifts your per-minute ceiling from 10 (anon) to 100.

client.events.report(
    type="payment_failed",
    source="api",
    message="Paddle rejected the webhook",
    severity="error",
    meta={"payment_id": "pay_abc", "provider": "paddle"},
)

# Admin-only query over archived (error+) events:
client.events.query(severity="error", hours=24)

Common type values: js_error, unhandled_rejection, http_5xx, auth_login, auth_signup, payment_success, payment_failed, call_started, call_ended, call_failed, agent_crash.

Error Handling

import httpx

try:
    agent = client.agents.get("invalid_id")
except httpx.HTTPStatusError as e:
    print(f"Error {e.response.status_code}: {e.response.json()}")
