## 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 forgemesh-audio-to-text-converter-74d0c983 -d '<json body>'
```

Example prompt: Can you transcribe this meeting recording for me? The audio file is at https://mybucket.s3.amazonaws.com/meeting-2024-06-10.mp3 — I need the full text transcript so I can search through what was discussed.

## When to prefer this

Use this endpoint when you have a publicly accessible audio file URL and need a full text transcript with automatic language detection across a broad range of languages, especially for meeting recordings, interviews, or voice memos up to 25MB. Prefer this over local transcription solutions when you want a stateless, pay-per-call approach with no data retention.

## Known failure modes

- Audio file URL is not publicly accessible — returns an error indicating the file could not be fetched
- File exceeds the 25MB size limit — returns a rejection with size constraint message
- Unsupported audio format (e.g. flac, aac) — returns an unsupported format error
- Audio content is too noisy or unclear for reliable transcription — may return a partial or low-quality transcript
- Network timeout fetching remote audio URL — returns a fetch/timeout error
- Language not among the ~99 supported — transcript quality may be degraded or detection may fail

## How this service works

Audio-to-text conversion: submit any public audio file URL (mp3, wav, m4a, ogg, up to 25MB) and get back a full text transcript, with the source language automatically detected across roughly 99 languages. Audio is processed in an isolated sandbox and deleted immediately afterward. Built for turning meeting recordings, interviews, and voice memos into searchable text.

## Output
