Example use cases
Legal precedent research on a topic
“Find me up to 10 published court opinions mentioning 'data privacy' AND 'GDPR' decided after 2020-01-01 — I want to see what federal courts have been saying about this.”
Track a specific case by docket number
“Look up the federal docket for case number 23-1027 and show me the filings associated with it.”
Litigation landscape for a company
“Search for court cases where 'Merck' appears in the case name, filed before 2023-12-31, and return up to 20 results so I can get a sense of their litigation history.”
Technical details
Endpoint
POSThttps://win.oneshotagent.com/v1/tools/find/record-court-cases?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to search legal court records — both published opinions and federal dockets — with flexible filtering by keyword, court, date, case name, or docket number. Prefer this over general web search when you need structured, authoritative legal case data rather than news articles or summaries.
Side effects
- No results found for overly narrow query combinations (court + date range + keyword)
- Invalid court ID returns an error or empty result
- Query string outside 1–500 character limit is rejected
- Date format not in YYYY-MM-DD format causes a parsing error
- Limit outside 1–20 range is rejected
- Rate limiting or payment failure (x402) if USDC payment is not processed
