Tools
Give an OpenRouter agent WebSearchTools and stream the answer in both sync and async runs.
"""Run `uv pip install ddgs` to install dependencies."""

# --- Async + Streaming ---
asyncio.run(agent.aprint_response("Whats happening in France?", stream=True))Run the Example
Set up your virtual environment
uv venv --python 3.12
source .venv/bin/activateInstall dependencies
uv pip install -U agno ddgs openaiExport 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 tool_use.py, then run:
