## 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-text-to-speech-via-pay-per-call-2e128270
```

Example prompt: Can you use GlianaAI's TTS-1 model to read this aloud: 'Welcome to our quarterly review. Today we'll cover sales performance and upcoming goals.' — pay per call in USDC, no account needed.

## When to prefer this

Choose this endpoint when you need on-demand text-to-speech synthesis without account registration or API key setup, especially when your agent can pay in USDC (Base, Solana, or Tempo) or card via x402/MPP. Ideal for autonomous agents that need pay-per-call audio generation without pre-committed subscriptions.

## Known failure modes

- Payment not settled — 402 response if USDC payment fails or is insufficient
- Invalid or missing prompt field — 400 validation error
- Model overload or unavailability — 503 or timeout
- Unsupported text content (e.g. too long) — may return error or truncated output
- Network failure during media URL retrieval after generation

## 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), an output object containing a media URL or JSON payload with the generated audio, and the amount charged in micro-USD (costMicroUsd).
