## 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-crossing-power-lookup-by-id-e6c0dd8c
```

Example prompt: Can you fetch the lilambd crossing resource with ID 'abc123' and tell me what data and attribution come back?

## When to prefer this

Use this endpoint when you need to retrieve a specific resource by a known ID from the lilambd crossing service and require structured output with a data array, item count, and source attribution. Best suited when you already have the target ID and want attributed, structured results rather than open-ended search.

## Known failure modes

- Unknown or invalid ID returns empty data array with count 0
- Payment not received results in HTTP 402 response before data is returned
- Malformed path parameter causes request to fail
- ID exists but has no associated records, returning count 0 and empty data

## 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 containing a 'data' array of records, a 'count' integer indicating how many results were found, and an 'attribution' string providing source licence information.
