## 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 aispace-x402-audio-quote-648fe898 -d '<json body>'
```

Example prompt: Before I commit any USDC, can you get me a price quote for transcribing an audio file using the AiSpace x402 audio endpoint on Venice so I know what it'll cost me in USDC on Base?

## When to prefer this

Use this endpoint when an agent needs to check the USDC cost of an audio processing request before committing payment via x402 on Base. Prefer this over directly calling the audio endpoint when operating under budget constraints, building approval workflows, or comparing costs across providers. This is the pre-flight cost check step in a pay-per-request audio pipeline.

## Known failure modes

- Invalid audio request parameters return an error response
- Network connectivity issues to x402.aispace.bot result in request failure
- Unsupported audio model or operation type may return a 400 error
- Quote may differ from final charge if parameters change between quote and execution
