Frequently Asked Questions

Which courts and cases are covered?
Coverage spans US federal and state courts, including the Supreme Court, the federal circuit courts of appeals, district courts and many state appellate courts. You can search everything at once or narrow to a single court using its short code, such as scotus, ca9 or nysd.

How many cases can I collect in one run?
Set maxItems to any number you need. The scraper pages through the results automatically until it reaches your limit, so you can pull a handful of leading cases or thousands of dockets in one run.

Can I filter by court and date?
Yes. You can restrict results to one court and to a date range using a filed-after and filed-before date, and sort by relevance, newest, oldest or most cited.

What is the difference between opinions and dockets?
Opinions return decided case law with citations, the deciding judges and the opinion text. Dockets return the case timeline with every party, attorney, law firm and filed document, which is useful for tracking active litigation.

What happens to fields that a case does not have?
Fields that a particular case does not carry are returned as null rather than dropped, so every row keeps the same shape and is easy to load into a spreadsheet or database.
