Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 glianaai-tts-2-text-to-speech-6bfd8f25
```

Example prompt: Use GlianaAI's TTS-2 model to read this aloud: 'Welcome to our platform. Your order has been confirmed and will arrive in three business days.' — pay per call in USDC, no API key needed.

## When to prefer this

Choose this endpoint when your AI agent needs to synthesize speech on-demand without pre-registering an API key, and when you want per-call micropayment billing in USDC via x402. It is ideal for serverless or autonomous agent pipelines that need TTS without subscription overhead.

## Known failure modes

- Payment insufficient or rejected — x402 payment header missing or underfunded
- Prompt field missing — 400 error if required 'prompt' body field is omitted
- Model unavailable — upstream TTS-2 service outage returns 5xx
- Prompt too long — may exceed model token/character limits
- Unsupported language or characters in prompt — model returns partial or empty audio output
