## 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 tts-emotion-controller-mcp-f2d9bfb0 -d '<json body>'
```

Example prompt: Convert this text to speech with a warm, cheerful emotional tone: 'Welcome back! We're so glad you're here today.'

## When to prefer this

Choose this endpoint when you need text-to-speech generation that goes beyond flat, robotic synthesis and requires expressive, emotion-controlled vocal delivery — for example, for interactive voice agents, audiobook production, customer service prompts, or emotionally nuanced content. Prefer this over standard TTS APIs when emotional register of the voice matters to the end-user experience.

## Known failure modes

- Empty or missing 'data' field returns an error or empty response
- Unsupported emotion type may be silently ignored or cause unexpected output
- Very long text inputs may exceed processing limits
- Payment failure via x402 protocol results in 402 response before processing begins
- Ambiguous or conflicting emotion instructions may produce neutral-sounding output
