Federal Litigation Risk Monitor is a real-time REST API that gives developers and data teams instant access to U.S. federal court litigation records from PACER — the official federal court document system — via the CourtListener RECAP Archive. With a single API call you can search over 500 million docket entries spanning every federal district court, appellate court, bankruptcy court, and the U.S. Supreme Court.
Search any company name, executive name, or legal entity and receive back structured, normalized JSON: case name, court, docket number, filing date, assigned judge, nature of suit, cause of action, jurisdiction type, and a direct link to the CourtListener case record. Drill deeper into any case to retrieve its complete docket entry timeline — every complaint, motion, order, and ruling filed in that proceeding.
Who is this for?
Hedge fund analysts and quantitative researchers use this API to surface undisclosed litigation risk in portfolio companies before earnings events or position entries. A securities class action filed in the Southern District of New York or an SEC enforcement action filed in D.D.C. can be detected within hours of filing — without a Westlaw or Bloomberg Law subscription.
Corporate legal teams and in-house counsel use it to monitor ongoing docket activity against their own entity and track competitor litigation exposure across jurisdictions.
M&A due diligence firms and private equity analysts run systematic litigation scans on acquisition targets, checking for pending product liability suits, IP disputes, ERISA class actions, and regulatory enforcement proceedings that may affect deal valuation.
Fintech compliance officers use it to screen counterparties, borrowers, and business partners against active federal proceedings before onboarding.
Investigative journalists and legal researchers use it to track patterns of litigation across industries, courts, and judges — identifying serial plaintiffs, repeat defendants, and case clustering that signals emerging regulatory risk.
Key capabilities:
Search federal cases by party name with optional filters for court jurisdiction, filing date range, and nature-of-suit code. Filter to specific courts such as the Southern District of New York for securities and finance, Northern District of California for technology, District of Delaware for corporate and M&A, D.D.C. for regulatory and government actions, or Southern District of Texas for energy. Filter by nature-of-suit code to isolate securities fraud cases, product liability, ERISA claims, patent disputes, or any of the 80+ federal suit categories.
Retrieve complete docket details for any individual case by its CourtListener ID, including full case name, judge assignment, jurisdiction type, termination date for closed cases, and a canonical URL.
Fetch paginated docket entries for any case — the individual events and filings that make up the case record — in reverse chronological order, with entry numbers, filing dates, and filing descriptions.
Search party name variants to discover all the exact legal names a company uses across federal proceedings before running a full case search — critical for entities that litigate under multiple subsidiary names.
Architecture: Fully stateless. No database, no polling, no persistent storage. Every request proxies CourtListener in real time and returns clean, normalized JSON.
Response format: All endpoints return consistent, paginated JSON with count, page, page_size, has_more, and results fields. All errors return a structured body with standard HTTP status codes.
Pricing comparison: Westlaw CourtAlert and Bloomberg Law docket monitoring cost $15,000 to $25,000 per year per seat. This API delivers the same underlying PACER data — normalized, filterable, and programmable — through a standard REST interface at a fraction of the cost, with no annual contracts.
Data source: All data originates from PACER (Public Access to Court Electronic Records) via the CourtListener RECAP Archive, operated by the non-profit Free Law Project. Data is provided for informational purposes only and does not constitute legal advice.
Each endpoint returns structured JSON data. The Search endpoint provides a list of cases with details like case name, court, and filing date. The Get Full Case Details endpoint returns comprehensive case information, while the Get Docket Entries endpoint lists individual filing events within a case.
Key fields include `case_name`, `court_id`, `docket_number`, `date_filed`, `nature_of_suit`, `cause_of_action`, and `url`. These fields provide essential information about each case and its filings.
The response data is organized in a paginated format, including fields like `count`, `page`, `page_size`, `has_more`, and `results`. Each result contains detailed information about cases or docket entries, making it easy to navigate.
Users can customize requests using parameters such as `party_name`, `court jurisdiction`, `filing date range`, and `nature-of-suit code`. These parameters help filter results to meet specific needs, such as searching for cases in a particular court.
The data originates from PACER (Public Access to Court Electronic Records) via the CourtListener RECAP Archive, ensuring access to official federal court records. This source is maintained by the non-profit Free Law Project.
Typical use cases include monitoring litigation risks for hedge funds, conducting due diligence for M&A, tracking competitor litigation, and screening business partners for active federal proceedings. This data helps inform strategic decisions.
Users can analyze the returned data to identify litigation trends, assess risks, and monitor ongoing cases. For example, filtering by nature-of-suit can help pinpoint specific legal issues relevant to a business or investment strategy.
Data accuracy is maintained through regular updates from PACER and the CourtListener Archive. The API provides real-time access to court records, ensuring users receive the most current and reliable information available.
