## 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 zeroreader-melotts-text-to-speech-40a6b6cf -d '<json body>'
```

Example prompt: Can you read this aloud and give me a WAV audio file: 'Welcome to ZeroReader, your source for the latest tech, gaming, AI, and crypto news.'

## When to prefer this

Choose this endpoint when you need to synthesize speech from text and want a WAV audio output via a pay-per-call micropayment API. Useful for agents that need lightweight TTS without managing long-term API subscriptions, especially when integrated with x402 payment flows.

## Known failure modes

- Empty or missing text input returns an error
- Text too long may cause timeout or truncation
- Unsupported characters or languages may produce degraded output
- Payment failure (402) if USDC payment not provided
- Server-side model errors returning 500
