Cursor

Cursor is an AI coding editor. With a custom OpenAI Base URL, Cursor can call ModelGo logical models.

Before you start

• Install Cursor.
• Create or copy an API key in the ModelGo console.
• Confirm a logical model name available to your API key in the model catalog.

1. Install Cursor

Visit the Cursor website and download the build for your operating system.

2. Open Cursor model settings

Open Cursor settings and go to Models.

3. Add and enable a model

Click Add model, enter a logical model name from the model catalog, and save it.

In Model Names, keep the models you want to use and disable the rest.

4. Configure the ModelGo endpoint

In Settings → Models → API Keys, configure the OpenAI-compatible endpoint:

If your Cursor release uses the alternate settings layout, enter the same ModelGo values there.

Click Verify or Save. Cursor may use slightly different labels in different releases, but the API key, Base URL, and model name have the same meaning.

5. Test the connection

Return to the Cursor chat, select the model you added, and send a simple message. A normal response confirms the integration.

You can also list the models available to the API key:

curl https://api.modelgo.ai/v1/models \
  -H "Authorization: Bearer $MODELGO_API_KEY"

Troubleshooting

401 or authentication errors

Make sure the API key is complete, has no extra spaces, and is entered in OpenAI API Key.

404 or endpoint errors

Use https://api.modelgo.ai/v1 as the Base URL. Do not append /chat/completions to it.

Verify fails or the model is unavailable

Check that the model name is a logical ModelGo model and that the model is enabled for the API key.

The chat returns no content

Run GET https://api.modelgo.ai/v1/models to verify connectivity and the key, then confirm the target model is enabled in Model Names.
