Spatius Python SDK

Python server SDK for creating Spatius avatar sessions.

Installation

pip install spatius

Install the optional Ogg Opus encoder support when you want the SDK to encode raw PCM before sending:

pip install "spatius[opus]"

Quick Start

import asyncio
from datetime import datetime, timedelta, timezone

from spatius import new_avatar_session


async def main():
    session = new_avatar_session(
        api_key="your-api-key",
        app_id="your-app-id",
        avatar_id="your-avatar-id",
        expire_at=datetime.now(timezone.utc) + timedelta(minutes=5),
        transport_frames=lambda frame, last: print(
            f"Received frame: {len(frame)} bytes, last={last}"
        ),
        on_error=lambda err: print(f"Session error: {err}"),
        on_close=lambda: print("Session closed"),
    )

    await session.init()
    connection_id = await session.start()
    print(f"Connected: {connection_id}")

    audio_data = b"..."  # mono PCM s16le audio bytes
    request_id = await session.send_audio(audio_data, end=True)
    print(f"Sent audio request: {request_id}")

    await asyncio.sleep(10)
    await session.close()


if __name__ == "__main__":
    asyncio.run(main())
