dial-sdk

Official Python SDK for Dial — phone numbers, SMS, WhatsApp, and voice calls for AI agents.

Install

pip install dial-sdk
# or
uv add dial-sdk

Requires Python 3.11+.

Quickstart

The client is async. Construct it with a DialConfig, then call its methods inside an async with block:

import asyncio
from dial_sdk import DialClient, DialConfig, SendMessageParams, MakeCallParams

async def main():
    async with DialClient(DialConfig(api_key="sk_live_...")) as dial:
        # List your numbers
        numbers = await dial.list_numbers()
        from_id = numbers[0].id

        # Send an SMS
        await dial.send_message(SendMessageParams(
            to="+15551234567",
            from_number_id=from_id,
            body="Hello from Dial",
        ))

        # Place an AI voice call
        call = await dial.make_call(MakeCallParams(
            to="+15551234567",
            from_number_id=from_id,
            outbound_instruction="You are a friendly assistant confirming an appointment.",
        ))
        print(call.id, call.status)

asyncio.run(main())

DialConfig.base_url defaults to https://api.getdial.ai. Override it for local or self-hosted setups.

Live events

Incoming messages and call transcripts stream via an async generator:

async with DialClient(DialConfig(api_key="sk_live_...")) as dial:
    async with dial.new_events_connection() as events:
        async for event in events:
            print(event)  # MessageEvent / CallEvent / CallTranscribed / ...
