## 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-1-hd-text-to-speech-035e7250
```

Example prompt: Use GlianaAI's tts-1-hd endpoint to read this aloud in high-definition audio: 'Welcome to our store. We're happy to have you here today.'

## When to prefer this

Choose this endpoint when you need high-definition text-to-speech audio generation without a pre-existing API key or account, and you want to pay per-call in USDC (Base, Solana, or Tempo) or by card via x402 micropayment protocol. Ideal for agents that need on-demand narration without subscription overhead.

## Known failure modes

- Missing or empty prompt field returns validation error
- Payment failure or insufficient USDC balance causes 402 rejection
- Prompt too long exceeds model context limits
- Network timeout during audio generation
- Unsupported characters or language in prompt may produce degraded output

## How this service works

One endpoint for 90+ generative AI models, live market data, SEC filings and identity APIs — image, video, music, speech, LLM chat, crypto and FX rates, DEX liquidity, gas, US company fundamentals and insider trades, document OCR and face matching. Pay per request in USDC on Tempo, Base, Solana, Algorand or BNB Chain with no signup, or top up a prepaid balance in rupiah.

## Output

Returns a JSON object with the model name used (tts-1-hd), an output object containing a media URL or JSON with the generated audio, and the amount charged in micro-USD (costMicroUsd).
