# CourtListener research
Search CourtListener's public opinion index and browse its court and judicial
person directories as normalized JSON.
## When to use this skill
- Search public opinions by text.
- Discover courts and retrieve one court record.
- Browse or look up public judicial-person records.
- Build an initial legal-research shortlist before opening primary documents.
## Setup
- Get a Crawlora API key at [crawlora.net](https://crawlora.net?utm_source=github&utm_medium=referral&utm_campaign=crawlora-skills).
- Set `CRAWLORA_API_KEY` in the environment before running the helper.
- The helper reads `CRAWLORA_API_KEY` from the environment and sends requests to `https://api.crawlora.net/api/v1`.
## How it works
Use `/courtlistener/search` for opinion text search, `/courtlistener/courts`
for court discovery/detail, and `/courtlistener/people` for public judicial
person records. Treat results as research leads and verify legal conclusions
against the underlying opinion and applicable jurisdiction.
