Run the Example

Set up your virtual environment

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

Install dependencies

uv pip install -U agno openai

Export your OpenRouter API key

export OPENROUTER_API_KEY="your_openrouter_api_key_here"

Use the full OpenRouter model ID

Replace each bare id="gpt-5.6-luna" with id="openai/gpt-5.6-luna". On the structured-output example, also replace id="gpt-4o-2024-08-06" with the same full Luna ID. Keep the JSON-mode/schema settings and other options. The OpenRouter catalog lists this model with tool and structured-output support; account and provider availability still apply.

Run the example

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

python basic.py
