## 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 agents-vimmerse-net-text-2-sound-effect-9cc4be38 -d '<json body>'
```

Example prompt: Generate a 8-second sound effect of a thunderstorm with heavy rain and distant thunder rumbling using the MMAudio model.

## When to prefer this

Choose this endpoint when you need to programmatically generate custom sound effects from text descriptions, especially for media production, game development, or app audio. Prefer ElevenLabsSE for shorter, precise foley-style effects and MMAudio for richer, more complex ambient or cinematic sounds. Use over stock sound libraries when you need unique, custom audio that doesn't exist as a pre-recorded asset.

## Known failure modes

- Invalid or empty prompt returns a 400 error
- Duration below minimum of 1 second is rejected
- Unsupported option value causes a validation error
- Generation model temporarily unavailable returns a 5xx error
- Insufficient credits result in a 402 payment required response

## How this service works

Sound effect from **`prompt`**. **`duration`**: length in seconds (default `5`).

## Output

Returns an audio result containing the generated sound effect clip as a URL or audio data in the results field, matching the requested duration and described characteristics.
