## 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 gedx402-aura-1-text-to-speech-4beb6cdd
```

Example prompt: Can you convert this text to spoken audio using the Aura-1 voice model: 'Welcome to our platform, we're glad to have you here.' Use the default voice and pay with USDC.

## When to prefer this

Choose this endpoint when you need pay-per-use text-to-speech without managing API keys or subscriptions, and you can pay via USDC on Base, Polygon, Arbitrum, World, or Solana. Ideal for agents that need to generate spoken audio on demand with crypto-native payments.

## Known failure modes

- Payment insufficient or failed — 402 response if USDC payment not attached or underpaid
- Text too long — may fail or truncate if input exceeds model limits
- Invalid voice ID — returns error if specified voice is not supported by Aura-1
- Network timeout — Cloudflare Worker may time out on long synthesis requests
- Unsupported chain — payment rejected if sent on an unsupported blockchain
