## 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 stability-ai-text-to-audio-4423005b -d '<json body>'
```

Example prompt: Generate a 30-second ambient forest soundscape with birds chirping and a light breeze, using stable-audio-2.5, and give me the result as an mp3.

## When to prefer this

Choose this endpoint when you need to generate original audio content — sound effects, music, or ambient audio — directly from a natural language text description using Stability AI's stable-audio models. Prefer this over audio-to-audio when you are starting from scratch with no source audio. Use stable-audio-2.5 for higher quality at fixed cost, or stable-audio-2 when you want step-based cost control.

## Known failure modes

- Invalid or missing prompt returns a 400 error
- Unsupported model name returns a validation error
- Duration value out of acceptable range returns an error
- Invalid output_format value (not mp3 or wav) returns a validation error
- Insufficient USDC balance or payment failure returns a 402 error
- Model overload or timeout may return a 503 or 504 error

## How this service works

Generate music or sound effects from a text prompt.

## Output

An audio file (mp3 or wav) generated from the provided text prompt, synthesized by Stability AI's stable-audio model. The response contains the binary audio content ready for playback or further processing.
