agentos-sdk-python 0.1.0

Async Python SDK for AgentOS APIs.

AgentOS SDK for Python

Async Python SDK for AgentOS APIs. The package is a thin client over AgentOS HTTP and SSE endpoints with small compatibility helpers for bearer tokens, stream callbacks, Pythonic method names, and request defaults.

Install

pip install agentos-sdk-python

For local development:

python3 -m venv .venv
.venv/bin/python -m pip install -e ".[dev]"

Quickstart

from agentos_sdk import AgentOSSDK


async def main():
    async with AgentOSSDK(base_url="http://localhost:8888") as sdk:
        version = await sdk.agentos.get_version()
        print(version)

        await sdk.agentos.register_bundle(
            {"bundleId": "com.demo.app", "appGroupId": "com.demo.group"}
        )

        tasks = await sdk.cronkit.list_tasks(limit=10)
        print(tasks)

AgentOSSDK also exposes TS-style camelCase aliases for common migration paths, such as registerBundle, listTasks, chatSimple, listModels, and loadTool.

Transport

The SDK uses httpx.AsyncClient and defaults to http://localhost:8888.

from agentos_sdk import AgentOSSDK

sdk = AgentOSSDK(
    base_url="http://localhost:8888",
    connect_timeout=5.0,
    receive_timeout=10.0,
)

Use async with AgentOSSDK(...) or call await sdk.aclose() when done.

Token Handling

sdk.agentos.register_bundle(...) stores the active app token. Protected facade methods in sdk.agentkit and sdk.cronkit use that token automatically.

If a protected call fails with HTTP 401, HTTP 403, or recognizable invalid-token text, the SDK re-runs registration for the same bundle once and retries the call.

AgentOS Events

from agentos_sdk import AgentOSEventHandler, AgentOSSDK


class Handler(AgentOSEventHandler):
    async def on_welcome(self, welcome):
        print("welcome", welcome)

    async def on_call_app(self, call):
        print("call app", call)

    async def on_done(self):
        print("subscription ended")

    async def on_error(self, error):
        raise error


async with AgentOSSDK() as sdk:
    await sdk.agentos.register_bundle({"bundleId": "com.demo.app"})
    await sdk.agentos.subscribe(Handler())

AgentKit

from agentos_sdk import AgentMessageHandler, AgentOSSDK, ToolReturn


class ChatHandler(AgentMessageHandler):
    async def on_message(self, session_id, message):
        print("message", session_id, message)

    async def on_chunk(self, session_id, chunk):
        print("chunk", session_id, chunk)

    async def on_function_call(self, session_id, function_call):
        return ToolReturn(function_call["id"], {"ok": True})

    async def on_done(self):
        print("done")

    async def on_error(self, error):
        raise error


async with AgentOSSDK() as sdk:
    await sdk.agentos.register_bundle({"bundleId": "com.demo.app"})
    session = await sdk.agentkit.init_session()
    await sdk.agentkit.chat(
        session,
        {"content": [{"type": "text", "message": "Hello"}]},
        ChatHandler(),
    )

Direct AgentKit methods include get_agent, create_agent, update_agent, delete_agent, init_session, init_simple, chat, chat_simple, history, stop, clear, callback, and stream_callback.

CronKit

async with AgentOSSDK() as sdk:
    await sdk.agentos.register_bundle({"bundleId": "com.demo.app"})
    task = await sdk.cronkit.create_task(
        request={
            "name": "Daily summary",
            "schedule": "0 9 * * *",
            "spec": {
                "systemPrompt": "You are a scheduled agent.",
                "content": [{"type": "text", "message": "Summarize today."}],
            },
        }
    )
    await sdk.cronkit.run_task_now(cron_id=task["cronId"])

CronKit create requests default concurrency to skipIfRunning, enabled to True, and spec.timeoutSeconds to 3600.

ModelKit

async with AgentOSSDK() as sdk:
    models = await sdk.modelkit.list_models()
    chat_models = await sdk.modelkit.list_models_by_task("chat")

    completion = await sdk.modelkit.chat.create(
        {
            "model": "qwen3-1.7b",
            "messages": [{"role": "user", "content": "Hello"}],
            "maxTokens": 128,
        }
    )

    async for chunk in sdk.modelkit.chat.create_stream(
        {"model": "qwen3-1.7b", "messages": [{"role": "user", "content": "Stream"}]}
    ):
        print(chunk)

ModelKit also supports:

• sdk.modelkit.embedding.create(...)
• sdk.modelkit.asr.transcribe(...)
• sdk.modelkit.tts.synthesize(...)
• sdk.modelkit.tts.list_voices()

ToolKit

async with AgentOSSDK() as sdk:
    tools = await sdk.toolkit.list_tool()
    definition = await sdk.toolkit.load_tool("tool-id")
    raw_json = definition.to_json() if definition else None

    async for event in sdk.toolkit.subscribe_tool_events("daemon-api-key"):
        print(event)

load_tool() returns an OpenToolDefinition wrapper that preserves the raw JSON definition. It does not execute tools or implement browser/daemon OpenTool bridging.

Direct Clients

The low-level clients are available for explicit-token or custom transport usage:

from agentos_sdk.clients import AgentKitClient, CronKitClient, ModelKitClient
from agentos_sdk.transport import ApiClient

api = ApiClient(base_url="http://localhost:8888")
agentkit = AgentKitClient(api)
agent = await agentkit.get_agent("bearer-token", "agent-id")
