## 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 courtlistener-court-detail-lookup-59d8f89b -d '<json body>'
```

Example prompt: Can you look up the CourtListener court details for 'scotus' — I need its full name, short name, citation string, and whether it's currently active?

## When to prefer this

Use this endpoint when you need authoritative metadata for a specific US court by its CourtListener identifier — especially when building legal citation tools, validating court references, or checking scraper/in-use status for data pipelines. Prefer it over general web search when you need structured, machine-readable court data without an API key.

## Known failure modes

- Invalid or unknown court ID returns an error or empty result
- CourtListener upstream API unavailable causes a proxy error
- Malformed request body (missing required fields) returns a 400-level error
- Rate limiting or payment failure returns a 402 or 429 response

## How this service works

Fetch full detail for one US court by court id (e.g. scotus) from CourtListener: full and short names, citation string, position, in-use status and scraper flags. Official CourtListener REST API, keyless read access. Useful for legal-data lookups.

## Output

Returns a structured record for the specified court including its full name, short name, citation string, integer position, boolean in-use status, and scraper-related flags as provided by the CourtListener REST API.
