+## Using gpt4free as an LLM Server for Bots (Clawbot/OpenClaw)
+
+### Overview
+This skill covers running gpt4free as a local LLM server with an OpenAI-compatible REST API, custom model routing (config.yaml), and integration with bots like Clawbot or OpenClaw.
+
+### Best Practices
+- Start the API server with: `python -m g4f --port 8080` (or use `g4f api --debug --port 8080`)
+- Use the `/v1` endpoint for OpenAI-compatible requests (e.g., POST to `http://localhost:8080/v1/chat/completions`)
+- Define custom model routes in `config.yaml` to aggregate/fallback across providers
+- Place `config.yaml` in your cookies directory (e.g., `~/.g4f/cookies/config.yaml`)
+- For Clawbot/OpenClaw, patch their config to point to your gpt4free server (see `patch-openclaw.py`)
+- Test with: `g4f client "Hello" --model openclaw` or Python client
+
+### Common Pitfalls
+- Not starting the server before connecting bots
+- Incorrect config.yaml path or syntax errors
+- Missing required Python dependencies (install with `pip install -r requirements.txt`)
+- Not exposing the correct port (default 8080)
+- Forgetting to patch bot configs to use your local endpoint
+
+### Workflow Steps
+1. Install and set up gpt4free (see README)
+2. Start the API server: `python -m g4f --port 8080`
+3. (Optional) Create or edit `config.yaml` for custom model routing:
+	 ```yaml
+	 models:
+		 - name: "openclaw"
+			 providers:
+				 - provider: "GeminiCLI"
+					 model: "gemini-3-flash-preview"
+					 condition: "quota.models.gemini-3-flash-preview.remainingFraction > 0 and error_count < 3"
+				 - provider: "Antigravity"
+					 model: "gemini-3-flash"
+				 - provider: "PollinationsAI"
+					 model: "openai"
+	 ```
+4. Patch your bot config (e.g., OpenClaw) to use `http://localhost:8080/v1` as the base URL (see `scripts/patch-openclaw.py`)
+5. Start your bot and verify it connects to gpt4free
+6. Monitor logs and test with the Python client or CLI
