# Test OpenClaw with Varion

## No-code preview
Open **Customer Dashboard → Test Varion → Chat History Test** or **Tool Schema Test**. Paste an exported OpenAI-compatible request. No OpenClaw/provider key is required.

## Real local comparison
1. Download the Varion Python or Node.js tester.
2. Copy your free Varion test key from **API keys**.
3. Set `VARION_TEST_PROVIDER=openclaw`.
4. Set `OPENCLAW_BASE_URL`, for example `http://127.0.0.1:3000/v1`.
5. Set `OPENCLAW_API_KEY` only when your gateway requires one.
6. Run the tester with a request JSON file or the built-in sample.

The tester asks Varion's optimise-only endpoint for the exact optimized request. Varion does not call OpenClaw. The OpenClaw key is sent only from your computer to your OpenClaw gateway. Prompt content is not stored by Varion. Only token/latency metrics are uploaded when metrics upload is enabled.
