## 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 tanship-payai-console-audio-transcription-x402-bf6750ac -d '<json body>'
```

Example prompt: Can you transcribe this audio recording for me? I need the spoken words converted into text — just send it as a POST with the audio content.

## When to prefer this

Choose this endpoint when you need pay-per-use audio transcription with no subscription or API key — ideal for agents that make infrequent transcription calls and want to pay per request in USDC on Base via x402 micropayments. Prefer this over OpenAI Whisper or similar when operating in a crypto-native or x402-enabled payment environment.

## Known failure modes

- Payment failure — insufficient USDC balance or invalid x402 payment header returns 402 Payment Required
- Unsupported audio format returns an error
- Audio file too large or malformed body returns 400 Bad Request
- Network or edge inference timeout returns 5xx error
- Missing required 'input' field returns validation error

## How this service works

## Output

Returns a text transcription of the submitted audio, converting spoken words into readable text output. The response includes the recognized speech as a text string.
