## 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 stratalize-federal-case-law-search-02aa7f78
```

Example prompt: Search federal case law for opinions about qualified immunity — filter to just the Second Circuit (ca2) — and show me the top results with citation counts and dates.

## When to prefer this

Choose this endpoint when an agent needs to search federal court opinions with citation counts and verifiable provenance. It is ideal for legal research workflows requiring cryptographic attestation of results, and when filtering by specific federal courts (e.g. SCOTUS, circuit courts, district courts). Prefer over raw CourtListener API access when you need signed, independently verifiable responses bundled with a trust receipt.

## Known failure modes

- Empty result set if query terms match no opinions in the CourtListener dataset
- Invalid court filter code returns error or falls back to all courts
- Overly broad queries may return low-relevance results
- Network or payment authorization failure returns no data
- Signature verification failure at trust.stratalize.com if receipt is tampered
