Cline / Cursor

Qubax is an OpenAI-compatible provider, so you can drop it into AI coding tools that let you set a custom base URL and API key. Below are the steps for Cline and Cursor.

Cline

Cline supports custom OpenAI-compatible endpoints. Point it at Qubax so every request routes through your account.

1. 1. Open the Cline panel in VS Code and click the settings (gear) icon.
2. 2. For API Provider, choose OpenAI Compatible.
3. 3. Set Base URL to:

https://api.qubax.ai/v1

1. 4. Paste your Qubax key into API Key:

qbx_live_your_api_key_here

1. 5. Enter a Model ID(for example, gpt-5).
2. 6. Click Let's go! to start a task.

Cursor

Cursor lets you add custom models through its OpenAI-compatible override. Configure it once and Qubax becomes available across Cursor Chat, Cmd K, and Agent modes.

1. 1. Open Cursor → Settings → Models.
2. 2. Scroll to the OpenAI API Key section and toggle Override OpenAI Base URL on.
3. 3. Set the base URL to:

https://api.qubax.ai/v1

1. 4. Paste your Qubax key into the API key field:

qbx_live_your_api_key_here

1. 5. Under Add Model, enter a model name such as gpt-5and click Verify.
2. 6. Select the new model from the model dropdown in Chat or Agent mode.

Using Qubax as the provider

Both tools treat Qubax as a standard OpenAI-compatible provider. Once the base URL and API key are set, model names map directly to Qubax model IDs. Requests, streaming, tool calls, and function calling all work out of the box.
