OpenAaaS Python SDK — Agent orchestration for Science

OpenAaaS Python SDK

A Pythonic SDK for the OpenAaaS Agent orchestration network, designed for researchers and scientists who want to submit compute tasks, manage results, and interact with AI agents from plain Python or Jupyter notebooks.

Installation

pip install pyopenaaas
# or with uv
uv add pyopenaaas

Development dependencies (optional):

pip install pyopenaaas[dev]   # includes test dependencies
# or
uv add --dev pyopenaaas       # add dev dependencies directly with uv

Quick Start

1. Register & configure

import pyopenaaas

# Option A: explicit credentials
client = pyopenaaas.Client(
    server_url="https://api.open-aaas.com",
    api_key="your-api-key",
)

# Option B: load from environment variables (OPENAAAS_SERVER_URL, OPENAAAS_API_KEY)
client = pyopenaaas.Client()

2. Discover services

with client:
    info = client.discover()
    print(info)

    services = client.list_services()
    for svc in services:
        print(svc.id, svc.name, svc.agent_status)

3. Submit a task

with client:
    task = client.submit_task(
        service_id="quantum-chemistry-v1",
        task_prompt="Calculate the ground state energy of H2O using CCSD(T)/cc-pVTZ",
        output_prompt="Return the total energy in Hartree and a brief summary",
        input_files=["h2o.xyz"],
    )
    print(task)

4. Wait for completion & download results

with client:
    task = client.wait_for_task(task.id, poll_interval=10.0)
    if task.is_success():
        # Get result files (actual results are here)
        paths = client.download_all_files(task.id, extract_zip=True)
        for p in paths:
            print("Saved:", p)

        # task.result contains execution metadata (e.g. stdout, file list)
        if task.result:
            print("Output files:", task.result.files)
            print("Stdout:", task.result.stdout)
    else:
        print("Task failed:", task.result)

Note: task.result only contains execution metadata (stdout, files, etc.). The actual result content of a completed task must be retrieved via client.list_files() and client.download_all_files().

Async Support

All methods have async counterparts via :class:AsyncClient:

async with pyopenaaas.AsyncClient(
    server_url="https://api.open-aaas.com",
    api_key="your-api-key",
) as client:
    services = await client.list_services()
    task = await client.submit_task("svc-1", "Run MD simulation")
    task = await client.wait_for_task(task.id)
    paths = await client.download_all_files(task.id)

In a Jupyter notebook or REPL you can also use the convenience helper:

info = pyopenaaas.run(
    pyopenaaas.AsyncClient(
        server_url="https://api.open-aaas.com",
        api_key="your-api-key",
    ).discover()
)

Jupyter Notebook users: pyopenaaas.run() uses asyncio.run() under the hood, which cannot be nested inside an existing event loop (the default in Jupyter). Instead, use await directly with :class:AsyncClient:

client = pyopenaaas.AsyncClient(
    server_url="https://api.open-aaas.com",
    api_key="your-api-key",
)
info = await client.discover()
services = await client.list_services()

Typical Research Workflow

import pyopenaaas

# 1. Initialise (reads OPENAAAS_API_KEY from env)
client = pyopenaaas.Client(server_url="https://api.open-aaas.com")

# 2. Pick a service
services = client.list_services()
ml_service = next(s for s in services if "ml" in s.name.lower())

# 3. Get usage instructions
usage = client.get_service_usage(ml_service.id)
print(usage.usage)

# 4. Submit a batch of experiments
session_id = "batch-2024-06-02"
tasks = []
for params in ["exp1.in", "exp2.in", "exp3.in"]:
    t = client.submit_task(
        service_id=ml_service.id,
        task_prompt="Train a GNN on the attached dataset",
        input_files=[params],
        session_id=session_id,
    )
    tasks.append(t)

# 5. Wait for all tasks
for t in tasks:
    final = client.wait_for_task(t.id, poll_interval=5.0)
    print(f"{final.id}: {final.status}")

# 6. Collect results
for t in tasks:
    if client.get_task(t.id).is_success():
        client.download_all_files(t.id, save_dir=f"results/{t.id}")

Configuration Priority

The SDK resolves settings in the following order (highest first):

1. Code kwargs — Client(server_url="...", api_key="...")
2. Environment variables — OPENAAAS_SERVER_URL, OPENAAAS_API_KEY
3. Defaults — https://api.open-aaas.com

Exception Hierarchy

OpenAaaSError
├── AuthenticationError  (401 / 403)
├── NotFoundError        (404)
├── ConflictError        (409)
├── RequestValidationError      (400)
├── NetworkError         (connectivity)
└── RequestTimeoutError         (request timeout)

Catch the base class to handle any SDK error:

from pyopenaaas.exceptions import OpenAaaSError

try:
    client.submit_task("bad-id", "...")
except OpenAaaSError as exc:
    print("SDK error:", exc)
