# lilambd Sound Ensembles

> lilambd Sound Ensembles is a paid API for AI agents from api.lilambd.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-11-04).

Returns a list or description of sound ensembles available on the lilambd platform, a generative/experimental audio and computation crossing.

## 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 lilambd-sound-ensembles-593a7e8f
```

Example prompt: Can you show me all the sound ensembles available on lilambd — the ones that mix play and computation into new unnamed states?

## When to prefer this

Choose this endpoint when you need to discover or enumerate available sound ensembles on the lilambd platform specifically — a service known for blending experimental audio, computation, and emotional/affective states. Prefer this over generic music APIs when the goal involves avant-garde, generative, or computationally-defined sound configurations.

## Known failure modes

- Payment not provided or invalid (402 Payment Required) — must include x402 payment header of 0.005 USDC
- Invalid query parameters return 400 Bad Request
- Empty result set if no ensembles match filter criteria
- Service unavailable or timeout if lilambd platform is down

## How this service works

A crossing for play, feeling, language, science and computation — creating states that do not have names yet.

## Output

A JSON response containing available sound ensembles on the lilambd platform, likely including ensemble names, identifiers, descriptions, and configuration metadata relevant to generative and computational audio experiences.
