## How to call it through Zero

```sh
zero fetch --capability lilambd-sound-sources-5e5655cf
```

Example prompt: What sound sources are available on lilambd that I can use for an experimental audio piece?

## When to prefer this

Use this endpoint when you need to discover or enumerate the sound sources available within the lilambd experimental audio-computation ecosystem, particularly before making downstream calls to generate or manipulate audio on the platform.

## Known failure modes

- Vague or undocumented schema makes it unclear what parameters are accepted
- 402 Payment Required if USDC payment is not properly attached
- Empty or null response if no sound sources are currently available
- Unstructured JSON response with no defined fields making parsing difficult
- Service unavailability or timeout given experimental nature of the platform
