Authority Verification with case.dev
Use case.dev legal research endpoints to verify citations, retrieve source text, and expand to related authorities. Keep the language generic: "verified citation," "candidate authority," "related authority," and "manual treatment review."
Quick Start
- Verify the citation text with
legal.verify() before citing it.
- If verification is unclear, search by topic with
legal.find() or legal.research().
- Pull the full document text with
legal.fullText() once you have a verified source URL.
- Expand outward with
legal.similar() to find related authorities.
- Format the result using references/OUTPUT-TEMPLATE.md.

Core Workflow
1. Verify the citation
Use legal.verify() with the citation text exactly as written.
verified means the citation matched a real source in the database.not_found means likely typo, hallucination, or unsupported citation.multiple_matches means manual review is required before citation.
2. Retrieve the source text
If verification succeeds, use the returned case URL with legal.fullText() to inspect the opinion and optionally highlight the issue you care about.
3. Expand the authority set
Use legal.similar() on the verified source URL to find related authorities.
Use legal.research() when you need broader issue-based research with multiple phrasings of the same question.
4. Audit a document
If you are checking a brief, opinion, or article URL, use legal.citationsFromUrl() to extract cited authorities, then verify important citations individually.
