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 / ...
