## 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-transcription-2-minute-audio-german-optimised-fa3cf3f0 -d '<json body>'
```

Example prompt: Transcribe this German voice memo for me — the file is at https://files.example.com/memo.m4a, it's under 2 minutes long, and the language is German (de).

## When to prefer this

Choose this endpoint when you need fast, cost-effective speech-to-text for short German-language audio clips (under 2 minutes) with GDPR-compliant processing in Germany. It is ideal for single voice memos, voicemails, or short dictations. For audio up to 10 minutes, use the sibling 10-minute endpoint. For diarised output with speaker separation, use the dedicated speaker-diarisation endpoint.

## Known failure modes

- Audio longer than 2 minutes — request rejected before payment settles
- Unsupported audio format — only mp3, m4a, ogg, wav, mp4 are accepted
- Invalid or inaccessible audio_url — URL must be publicly reachable over HTTPS
- Missing both audio_url and audio_base64 — one must be provided
- Language code not supported — falls back to auto-detection or returns error
- File too large to process within time constraints
