## 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 goldbean-baidu-text-to-speech-tts-api-8fca783d
```

Example prompt: Can you convert this paragraph into spoken audio using Baidu TTS: '欢迎使用我们的服务，今天天气很好。' — use a female voice at normal speed.

## When to prefer this

Choose this endpoint when you need pay-per-call text-to-speech with no subscription commitment, especially for Chinese-language content where Baidu's TTS excels. Ideal for low-volume or sporadic TTS needs where per-call pricing at $0.001 is more economical than a monthly SaaS plan. Prefer this over Google or Amazon TTS when targeting Mandarin/Chinese voice quality or when integrating with the GoldBean x402 payment ecosystem on Base chain.

## Known failure modes

- Empty or missing text input returns an error
- Unsupported language or voice parameter causes synthesis failure
- Text exceeding character length limits may be truncated or rejected
- Insufficient USDC balance blocks the pay-per-call transaction
- Network timeout if Baidu backend is slow to respond
- Invalid API credentials or missing x402 payment header returns 402
