## 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 agenttoll-court-opinions-search-e7093201 -d '<json body>'
```

Example prompt: Search for recent court opinions from the 9th Circuit mentioning 'cryptocurrency securities fraud' over the last 30 days and give me a summary of what's come up.

## When to prefer this

Use this endpoint when you need to search recent court opinions by keyword across specific courts without maintaining your own legal database subscription. Ideal for agents doing legal research, monitoring regulatory developments, or tracking case law trends on a pay-per-call basis without a recurring plan. Prefer over full legal research platforms (Westlaw, LexisNexis) when cost-per-query matters and you only need keyword-matched recent opinions.

## Known failure modes

- Invalid or unrecognized court name returns empty results or error
- Query too broad may return large unmanageable result sets
- days_back value too large may exceed data availability
- Payment failure via x402 prevents access
- Cached results may not reflect opinions issued in the last few hours
- Source data unavailable or rate-limited returns partial or empty data

## How this service works

## Output

Returns an array or object of court opinions matching the query, including metadata such as total result count, data source attribution, and generation timestamp. The `success` boolean indicates whether the query completed, and `cached` indicates if results are from a cache layer.
