## 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 agishub-text-to-speech-audio-speak-dffe514e -d '<json body>'
```

Example prompt: Can you read out this text in French and give me the audio file: 'Bonjour, bienvenue sur notre plateforme d'intelligence artificielle'?

## When to prefer this

Choose this endpoint when you need a quick, multilingual text-to-speech conversion that returns base64-encoded MP3 audio via a simple GET request with pay-per-call pricing at $0.05 USDC. It is especially suitable for agents that need on-demand audio generation in one of six supported languages (English, Spanish, French, Chinese, Japanese, Korean) without managing a subscription or API key — just an x402-compatible payment flow.

## Known failure modes

- Empty or missing 'text' query parameter returns a validation error
- Unsupported language code outside the enum (en, es, fr, zh, jp, kr) causes a bad request error
- Text that is too long may result in a timeout or truncation
- Payment failure via x402 protocol blocks the request before synthesis
- Network or upstream TTS engine errors may return a 5xx response
