## Local development

```bash
npm install
npm run dev
```

## Production build

```bash
npm install
npm run build
```

The deployable site is produced in `dist/`.

## Verification API

The production build reads:

```env
VITE_VERIFY_API_URL=/cc-api/api/ai/verify/public
```

The application first sends a JSON POST containing `query`, `certificate_id` and `hash`. If it is not accepted, it attempts a GET request. Adjust `verifyRemote()` in `src/main.tsx` after confirming the exact CopyrightChain public endpoint schema.

Demo verification ID:
