## 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-1af4fa1d -d '<json body>'
```

Example prompt: Can you read this aloud for me? Convert the following paragraph to speech audio using a natural English voice: 'Welcome to our platform. We're glad to have you here.'

## When to prefer this

Choose this endpoint when you need high-quality, natural-sounding TTS audio via Microsoft Edge voices, especially in a pay-per-use context on Base chain without needing a subscription. Good for lightweight, on-demand narration tasks where Azure Cognitive Services or Google TTS subscriptions are overkill.

## Known failure modes

- Empty or missing text input returns an error
- Unsupported language or voice identifier causes synthesis failure
- Text too long may be rejected or truncated
- Network timeout on the upstream Edge TTS service
- Invalid or malformed request body returns 400 error
- Payment failure (insufficient USDC balance) returns 402

## How this service works

400+ paid API endpoints. Social media, AI, crypto, finance, weather, ecommerce, tools. Pay per request with USDC on Base chain.
