## 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-science-subfields-lookup-c20f90d9
```

Example prompt: Can you give me the full list of science subfields from the Lilambd crossing platform — I want to see how it categorizes scientific disciplines?

## When to prefer this

Prefer this endpoint when you specifically want to retrieve science subfield classifications from the Lilambd platform, particularly if you are exploring interdisciplinary or unconventional science taxonomies that blend computation, language, and feeling. Avoid if you need a comprehensive, authoritative taxonomy of scientific fields — this service appears experimental and niche.

## Known failure modes

- Payment not completed — returns 402 if the x402 payment of $0.005 USDC is not provided
- Malformed query parameters may return a 400 error or empty result
- API may return sparse or vague data given the low crawl quality score and minimal schema documentation
- Endpoint may return an empty or unexpected JSON structure if the backend is experimental or incomplete

## 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 a structured list of science subfields as recognized by the Lilambd platform, potentially including names, descriptions, or classifications of scientific disciplines.
