Common checks

• Connection succeeded: the current key, model, and endpoint can be used normally. Next, go to Fast setup or Official client setup.
• Model not found: the model name is usually typed incorrectly. Copy the full name from Models and channels, then try again.
• Browser request failed or CORS: first copy the curl command from this page and test it in your local terminal. If the terminal works but the browser fails, it is usually a browser environment or cross-origin limitation.
