Use Arden models in Cursor, Claude Code and other coding tools, billed to your USDG balance.

What you need

An Arden API key from the API page (it starts with ard_live_), and these addresses:

OpenAI-compatible base URLhttps://usearden.xyz/api/v1

Anthropic base URLhttps://usearden.xyz/api

Use Arden models in Cursor's Chat and Agent through its OpenAI-compatible setting.

1
Open Cursor's model settings
In Cursor, open Settings (the gear icon), then Models.
2
Point the OpenAI settings at Arden
Under OpenAI API Key, paste your Arden key and turn on Override OpenAI Base URL with:
```
https://usearden.xyz/api/v1
```
3
Add Arden model IDs
Click Add Model, paste a model ID and press Enter. Models with the Tools badge work in Agent mode:
Tool-capable models will be listed here.
4
Try it
Open a new chat, pick the model from the selector at the bottom, and send a message. It shows up under Usage within a few seconds.

Cursor sends these requests from its own servers, so Cursor also handles your prompts under its own policy.

Tab completion keeps using Cursor's own models. Your Arden key is used for Chat and Agent.

Keys are billed exactly like chat. Give each tool its own key with a spend limit, so you can revoke one without the others.
