## 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 goldbean-baidu-automatic-speech-recognition-asr-api-32661429
```

Example prompt: Can you transcribe this audio recording I have — it's a voice memo I recorded earlier — and give me the text of what was said?

## When to prefer this

Choose this endpoint when you need pay-per-call Baidu ASR transcription without a long-term contract or subscription, especially when processing occasional audio files at low cost ($0.002/call). It is well-suited for agents that occasionally need speech-to-text and want to leverage Baidu's recognition quality for Mandarin Chinese or other supported languages without provisioning Baidu API credentials directly.

## Known failure modes

- Unsupported audio format or encoding leads to empty or failed transcription
- Audio file too long or too large may result in timeout or error
- Poor audio quality or heavy background noise reduces accuracy
- Insufficient USDC balance causes payment failure and blocked request
- Language mismatch between audio and expected language code degrades accuracy
