## 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-34b82a93 -d '<json body>'
```

Example prompt: Can you read out this paragraph using a natural-sounding English voice: 'The quick brown fox jumps over the lazy dog. Edge TTS is a fast and affordable way to generate speech from text.'

## When to prefer this

Choose this endpoint when you need fast, affordable text-to-speech synthesis without managing your own TTS infrastructure. It is ideal for agents needing to generate voice audio per-request with pay-as-you-go USDC billing on Base chain, and when Microsoft Edge TTS voice quality is acceptable. Prefer over Azure Cognitive Services or AWS Polly when you want crypto-native micropayments without API key management.

## Known failure modes

- Empty or missing text input returns an error
- Unsupported voice or language code causes failure
- Payment of 0.08 USDC not received results in 402 response
- Text too long may be truncated or rejected
- Network timeout on large text synthesis requests

## How this service works

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

## Output

Returns audio data (likely base64-encoded or binary audio) representing the synthesized speech of the provided text, generated using Microsoft Edge TTS voices.
