## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability nexari-transcribe-10min-german-optimised-whisper-399992fe -d '<json body>'
```

Example prompt: Please transcribe this German voice memo for me — the audio is at https://files.example.com/memo.m4a, it's in German, and the filename is memo.m4a.

## When to prefer this

Choose this endpoint when you need GDPR-compliant German-language speech-to-text processing hosted within Germany, for audio files under 10 minutes. It is ideal when data residency in Germany is required, when the audio is primarily in German (though other languages and auto-detection are supported), and when you want a flat per-call price of $0.10 USDC. Prefer the per-minute billing sibling endpoint for files between 10 and 50 minutes, or the speaker-diarisation endpoint when you need speaker separation.

## Known failure modes

- Audio file exceeds 10-minute limit — request is rejected before payment settles
- Unsupported audio format — only mp3, m4a, ogg, wav, mp4 are accepted
- Audio URL is not publicly accessible or returns an error
- Base64-encoded audio is malformed or too large
- Language code not recognised
- Network or processing timeout for large files near the limit
- GDPR fields (privacy_contact, accept_terms_hash) missing for B2B usage
