# Use a Claude API key in Cursor

Cursor lets you bring your own Anthropic key, which means you can run Claude in Cursor on discounted prepaid balance instead of a bundled plan.

## Three-step setup

1. Open Cursor → Settings → Models → Anthropic API.
2. Set the base URL to https://api.apitoken.sale and paste your sk-pool-••• key.
3. Pick a model such as claude-opus-4-8 and start coding.

## Configuration

```
# Cursor → Settings → Models → Anthropic API
Base URL : https://api.apitoken.sale
API key  : sk-pool-•••
Model    : claude-opus-4-8
```

## Troubleshooting

- Cursor ignores the key: confirm you edited the Anthropic provider, not OpenAI.
- Model not found: set a current model ID like claude-opus-4-8.
- 401: re-check the base URL and that the key was pasted in full.

Once connected, every supported Claude model is available on the same key and balance.

## Your Claude API key in Cursor for any language

The key is language-agnostic — Cursor uses it for Python, JavaScript, TypeScript, Go, Rust or any project, on Windows, macOS and Linux. You are configuring the model provider, not the language.

## Frequently asked questions

### Can I use my own Claude key in Cursor?

Yes. Cursor's Anthropic provider accepts a custom base URL and key, so you can point it at apiToken.sale.

### Do I still need Cursor Pro?

You can run Claude through your own API key and balance; features that require Cursor's own plan are separate from the model provider.

### Does the Claude API key work in Cursor on Windows and Mac?

Yes — the Anthropic provider setting is the same across Windows, macOS and Linux.
