Auth

Authenticate AgentOSClient calls with the central OS security key.

auth.py
"""Authenticate AgentOSClient calls with the central OS security key.

Start ``_server.py`` with OS_SECURITY_KEY set, then run this file with the same
value. See lesson ``07_security`` in Phase 2 for JWT, RBAC, and service-account
authentication.

Prerequisites: start ``_server.py`` with OS_SECURITY_KEY and OPENAI_API_KEY.
Run: .venvs/demo/bin/python cookbook/05_agent_os/03_python_client/06_auth.py
Try: remove the Authorization header and observe the server return HTTP 401.

Run the Example

Set up your virtual environment

uv venv --python 3.12
source .venv/bin/activate

Install dependencies

uv pip install -U agno fastapi

Export environment variables

export OS_SECURITY_KEY="your_os_security_key_here"

Start the secured companion server

Follow the shared-server setup to obtain the cookbook files and server dependencies. Stop any unsecured copy of _server.py, then start it in a terminal with both OPENAI_API_KEY and the same OS_SECURITY_KEY used by this client:

python cookbook/05_agent_os/03_python_client/_server.py

Keep that server running on port 7778 while you run the client in another terminal.

Run the example

Save the code above as auth.py, then run:

python auth.py
