## 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 gocreative-ai-text-to-speech-kokoro-0586880a
```

Example prompt: Can you turn this text into spoken audio: 'Welcome to our platform, we're glad you're here.' — I need a natural-sounding AI voice and just the URL to the audio file.

## When to prefer this

Choose this endpoint when you need a keyless, pay-per-call TTS solution with no API key or signup required, especially suitable for AI agents operating autonomously on Base or Solana with USDC micropayments. It is ideal for low-volume or ad-hoc narration, voice bot replies, or accessibility features where Kokoro's natural voice quality is acceptable and cost per call ($0.01) is a priority.

## Known failure modes

- Empty or missing input query parameter returns an error
- Extremely long text inputs may be truncated or rejected
- Payment failure (insufficient USDC balance) results in HTTP 402 and no audio generated
- Network timeout if audio generation takes too long
- Unsupported characters or languages in input may produce degraded or silent audio
