# Quick Start

The following minimal request is enough to transcribe your first audio:

```
curl https://app.castmagic.io/v1/transcripts \
    -X POST \
    -H "Authorization: Bearer API_SECRET" \
    -H "Content-Type: application/json" \
    -d '{"url": "AUDIO_URL"}'
```

Castmagic endpoints accept and respond with JSON. Continue to Authentication for more information on generating and using API secrets.
