## 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 kiteendpoints-ai-edge-tts-text-to-speech-ce6cddca -d '<json body>'
```

Example prompt: Can you convert this paragraph to spoken audio using a natural-sounding English voice: 'Welcome to our platform. We are glad to have you here.' Use a standard male or female Edge TTS voice.

## When to prefer this

Use this endpoint when you need fast, cost-effective text-to-speech synthesis via Microsoft Edge TTS voices and are already operating within the KiteEndpoints x402/USDC payment ecosystem. Good for agents that need on-demand narration without managing separate TTS API credentials.

## Known failure modes

- Empty or missing text input returns an error
- Unsupported voice or language code causes failure
- Text too long may exceed limits
- Payment failure (insufficient USDC balance) results in 402 response
- Service unavailability from underlying Edge TTS provider
