Quick Start

import asyncio
from onebudd import OneBuddClient

async def main():
    client = OneBuddClient("pk_test_xxx")
    
    # Set up callbacks
    client.on_audio(lambda audio: play(audio))
    client.on_transcript(lambda t: print(f"{t.role}: {t.text}"))
    
    # Connect
    session = await client.start_session()
    print(f"Connected: {session.id}")
    
    # Run message loop in background
    asyncio.create_task(client.run())
    
    # Send text (skips speech recognition)
    await client.send_message("Hello!")
    
    # Or send audio (PCM 16kHz mono 16-bit)
    await client.send_audio(audio_bytes)
    
    # End session
    await client.end_session()

asyncio.run(main())

Configuration

client = OneBuddClient(
    api_key="pk_xxx",
    base_url="wss://api.onebudd.com",  # WebSocket URL
    auto_reconnect=True,                # Auto-reconnect on disconnect
    max_reconnect_attempts=5,           # Max attempts
    reconnect_delay_ms=1000,            # Base delay (exponential backoff)
)

Streaming Audio from Microphone

import pyaudio
import asyncio
from onebudd import OneBuddClient

async def stream_microphone():
    client = OneBuddClient("pk_xxx")
    await client.start_session()
    asyncio.create_task(client.run())
    
    # Set up PyAudio
    p = pyaudio.PyAudio()
    stream = p.open(
        format=pyaudio.paInt16,
        channels=1,
        rate=16000,
        input=True,
        frames_per_buffer=3200,  # 200ms at 16kHz
    )
    
    try:
        while True:
            audio_chunk = stream.read(3200)
            await client.send_audio(audio_chunk)
            await asyncio.sleep(0.01)
    finally:
        stream.stop_stream()
        stream.close()
        p.terminate()
        await client.end_session()

asyncio.run(stream_microphone())

Error Handling

def handle_error(error: Error):
    print(f"Error [{error.code}]: {error.message}")
    if error.fatal:
        print("Connection will be closed")

client.on_error(handle_error)
