+### Quick Validation Checklist
+
+After deploying, you can validate the wrapper end-to-end in a few commands:
+
+```bash
+# 1) Health endpoint should return 200
+curl -i https://your-worker.workers.dev/health
+
+# 2) Models endpoint should return JSON model list
+curl -sS https://your-worker.workers.dev/v1/models \
+  -H "Authorization: Bearer sk-your-api-key-here"
+
+# 3) Non-streaming chat completion sanity check
+curl -sS https://your-worker.workers.dev/v1/chat/completions \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer sk-your-api-key-here" \
+  -d '{
+    "model": "gpt-4",
+    "messages": [{"role": "user", "content": "Reply with: wrapper is working"}],
+    "stream": false
+  }'
+```
+
+If step 1 fails, deployment/networking is likely the issue. If step 2 or 3 fails with `401`, double-check your API key and request headers.
