# lilambd Kinds Lookup

> lilambd Kinds Lookup is a paid API for AI agents from api.lilambd.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-11-02).

## 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-kinds-lookup-6f52cf74
```

Example prompt: Can you look up the lilambd kind with ID 'em-joy-42' and tell me what data and attribution it returns?

## When to prefer this

Use this endpoint when you need to retrieve a specific 'kind' entity from the lilambd crossing system by its exact ID. Prefer this when you have a known kind ID and want its associated data along with attribution metadata. Not suitable for listing all kinds or performing open-ended search without a specific ID.

## Known failure modes

- Unknown or invalid ID returns empty data array with count 0
- Malformed path parameter may result in a 400 or 404 HTTP error
- Payment not completed (x402) results in a 402 Payment Required response
- No additional query parameters are required but unexpected ones may be ignored or rejected

## How this service works

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

## Output

Returns a JSON object with a 'data' array containing the kind's associated records, a 'count' integer indicating the number of items, and an 'attribution' string providing the source licence line for the content.
