Integration details
Description
OpenCase checks legal writing against the law. It confirms that the cases, statutes, and regulations a brief, memo, or contract cites exist as cited, that quoted language appears word for word in the source, and whether a case is still good law. It also answers legal questions with authority it has retrieved and verified. Tools: - Verify citations in legal text: finds every citation in a document and checks each one. - Resolve legal citations: checks a list of citations and returns source details. - Check a quotation: confirms a quote appears word for word in the authority, honoring ellipses and brackets. - Get legal authority: retrieves one authority's metadata and text. - Check case validity and Get case treatments: report a case's good-law flag and the decisions that cited it. - Research a legal question and Review document against law: return cited answers and grounded findings. - Detect legal citations: lists citations and their positions without checking them. - Search federal court dockets and Get a docket filing: search CourtListener RECAP. Coverage spans US federal and state law and many other jurisdictions. OpenCase is a research tool, not a lawyer: a citation it cannot find may still exist, and a verified citation still needs a lawyer's judgment. Requires an OpenCase account, which you can create while connecting. Free accounts include 10 tool calls a day; a paid plan removes the limit.
