How this service works
Federal court opinion search via CourtListener. Search 10M+ opinions, docket records, and case history. Pay-per-request via x402 protocol on Base mainnet.
Output
A list of federal court cases involving the specified company, including case names, docket numbers, case types (antitrust, securities, IP, employment, etc.), court jurisdictions, filing dates, and parties involved.
Example use cases
Assess vendor litigation risk before partnership
“Before we sign a deal with this supplier, can you pull up all their federal court cases? I need to see if they have a history of antitrust issues, IP disputes, or employment lawsuits that might be a red flag.”
Competitive intelligence on rival company lawsuits
“I'm doing a competitive analysis on our main competitor. Search for all their federal court cases — especially antitrust and securities litigation — so I can understand what legal challenges they're facing.”
Due diligence for acquisition target review
“We're considering acquiring TechCorp. Pull together all federal court cases they've been involved in — I want the full picture of antitrust, employment, IP, and any other litigation before we move forward with the deal.”
Technical details
Endpoint
GEThttps://legal.memoryapi.org/x402/legal/companyWhen to prefer
Use this endpoint when you need a broad sweep of all federal litigation for a specific company across all case types. Prefer this over the case-detail endpoint when you want an overview rather than details on a specific docket, and over the general opinion search when the query is company-centric rather than topic-centric.
Side effects
- Company name not found or too ambiguous — returns empty result or requires more specific identifier
- Company has no federal court cases on record — returns empty list
- Rate limiting or payment failure via x402 protocol — returns 402 Payment Required
- Network timeout or upstream CourtListener/RECAP Archive unavailability — returns 5xx error
- Misspelled or partial company name yields incomplete results
