## 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-fields-lookup-aee3a2a7
```

Example prompt: Can you fetch the details for science field ID 'quantum-cognition' from the lilambd crossing and tell me what it covers?

## When to prefer this

Choose this endpoint when you need structured metadata about a specific scientific field by ID from the lilambd crossing platform, particularly for interdisciplinary, emergent, or unconventionally framed fields that may not appear in mainstream academic databases. Prefer it when exploring the intersection of computation, language, play, and feeling as scientific domains.

## Known failure modes

- Invalid or unknown field_id returns a 404 or error JSON
- Missing field_id path parameter causes a 400 bad request
- Payment not completed (402) blocks access to the response
- Server errors (500) if the field database is unavailable
- Malformed field_id format may return an empty or null result

## How this service works

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

## Output

A JSON object containing metadata and descriptive information about the requested scientific field, including its definition, related concepts, and any associated interdisciplinary connections as catalogued by the lilambd platform.
