## FAQ

### What scoring methods are available?

The engine supports Weighted Sum (SAW), Weighted Product (WPM), and TOPSIS (closeness to ideal solution).

### Does the server require an API key?

The public remote server runs in open mode with no key (limited to 15 calls/day), but paid plans provide an API key via Stripe.
