+## End-to-End Example
+
+Here is a complete end-to-end example showing how a developer can go from zero to making an inference call:
+
+```python
+import os
+from opengradient import OpenGradientClient
+
+# Initialize the client
+client = OpenGradientClient(
+    api_key=os.environ["OPENGRADIENT_API_KEY"],
+    tee_url=os.environ.get("OPENGRADIENT_TEE_URL", "https://tee.opengradient.ai"),
+)
+
+# List available models
+models = client.list_models()
+print(f"Available models: {[m.id for m in models]}")
+
+if models:
+    model_id = models[0].id
+    # Prepare input data
+    input_data = {"text": "Hello, world!"}
+    try:
+        result = client.inference.predict(model_id, input_data)
+        print(f"Inference result: {result}")
+    except Exception as e:
+        print(f"Inference failed: {e}")
+```
+
+This example demonstrates:
+1. Client initialization with API key
+2. Listing available models
+3. Making an inference call with error handling
+4. Environment-based configuration
