## How to call it through Zero

```sh
zero fetch --capability lilambd-science-fields-4f48f7fa
```

Example prompt: Can you fetch the list of science fields available on the lilambd crossing platform so I can see what interdisciplinary domains they cover?

## When to prefer this

Choose this endpoint when you need to discover or enumerate the science and interdisciplinary domains offered by the lilambd crossing platform, particularly when exploring topics that blend computation, language, play, and feeling in novel ways not covered by mainstream academic taxonomy APIs.

## Known failure modes

- Payment not provided or insufficient (402 Payment Required)
- Invalid or missing query parameters return an error or empty result
- Service unavailable or timeout if the lilambd API is down
- Malformed JSON response if the platform is in a degraded state
- Empty field list if no fields are currently published

## 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 listing the science fields or domain categories available on the lilambd crossing platform, potentially including field names, descriptions, and metadata about interdisciplinary intersections of play, feeling, language, science, and computation.
