## 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 maxwell-international-courts-search-5c10efe0
```

Example prompt: Can you search for court opinions about fair use and copyright infringement — I want to see what cases and courts have weighed in on that topic?

## When to prefer this

Choose this endpoint when you need fast, structured lookup of court opinions and legal case metadata by keyword — particularly useful for legal research agents that need case names, filing courts, and dates without requiring full-text document retrieval. Prefer this over general web search when structured legal data with court attribution is needed.

## Known failure modes

- Empty hits array if no court documents match the query
- Missing or malformed query parameter returns an error
- Rate limiting or payment failure if x402 micropayment not processed
- Service unavailability due to domain-for-sale status of underlying host
- Cache miss may result in slower response times

## How this service works

US court opinion search on CourtListener (Free Law Project): case name, court, date filed, docket number and the opinion link. Short queries match as a phrase (?q=fair use), longer ones need every word. Cached; a query not yet cached is fetched live.

## Output

Returns a JSON object containing an array of matching court opinion hits (each with court name, case name, and filing date), a total count of results, a boolean match indicator, the original query string, and a cache status field indicating whether the result was served from cache.
