Cursor setup

Cursor connects to Claudexia through its OpenAI-compatible mode with your own key.

Connecting

1. Open Cursor → Settings → Models.
2. Turn on OpenAI API Key and paste your Claudexia key.
3. Turn on Override OpenAI Base URL and enter https://api.claudexia.tech/v1.
4. Click Add model and enter the Cursor model name from the table below.
5. Click Verify and pick the model in the chat.

Model name for Cursor

Cursor does not accept its own model names with a third-party key, so Claude and GPT models have a separate name for Cursor: for example cursor5 for Claude Opus 5. Models from other developers (Gemini, DeepSeek, Qwen and others) use their API name.

The table can lag behind the catalog. If a Claude or GPT model you need is missing, ask support for its name.

Cursor limitations

• A custom Base URL applies to all models: built-in ones (Composer, Auto) may stop working while it is on.
• You cannot switch models in the middle of a chat: add the ones you need in advance.
• If Verify fails or the Base URL switch is missing, install the Cline or Continue extension in Cursor: see VS Code and others.

When something goes wrong

Model not found

Enter the name from the table exactly, with no spaces or extra characters. If a model has no Cursor name, use its ID from GET /v1/models.

Authentication errors

The key must start with sk_cdx_, contain no spaces or line breaks, and stay active in the API Keys section.
