## FAQ

### How much does it cost to use Loopcut?

Costs are based on credits where 1 credit equals $0.01. Every paid tool provides a free quote before starting a job.

### Can I use Loopcut without installing a separate app?

Yes, you do not need the Loopcut app as any Blender installation packs the scene, and it works as a hosted connector for Claude.ai and ChatGPT.

### What happens if a job fails?

If a job fails, your credits are refunded.

### How do I authenticate with the server?

The first call opens a browser for sign-in, or you can use a LOOPCUT_API_KEY for environments like CI.
