## 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 elevenlabs-sound-effects-generator-via-sol-blockrun-ai-125fce01 -d '<json body>'
```

Example prompt: Generate a 3-second sound effect of a thunderclap with heavy rain, output it as a WAV file, and set prompt influence to 0.8.

## When to prefer this

Choose this endpoint when you need programmatic, API-driven sound effect generation backed by ElevenLabs quality, especially within a Solana/x402 payment workflow. It is ideal when you want precise control over audio format (MP3, WAV, opus, PCM), clip duration, and prompt adherence. Prefer this over generic TTS endpoints when the goal is non-speech audio — environmental sounds, foley, game assets, or cinematic effects rather than voice synthesis.

## Known failure modes

- Invalid or missing text description returns a 400 error
- Duration outside 0.5–22 second range may be rejected or clamped
- Unsupported response_format value returns a validation error
- Payment failure or insufficient USDC balance blocks the request
- Model ID not recognized returns an unknown model error
- Very vague prompts may produce generic or mismatched audio output
