CourtListener Opinions Scraper

Scrape US court opinions from CourtListener by keyword or catch the latest rulings, up to a million per run. Every opinion returns with its full case metadata, citation, judge, and court. No API key required.

CourtListener's official API requires registration, throttles requests, and limits the shape of data you can pull. This reads the public opinion search directly, letting you pull case law by search term or scrape the newest decisions as they are filed. Each match drops into your dataset as one clean row, ready for analysis.

Who uses itWhat they scrape CourtListener for
Legal data analystsChart how often a specific judge cites precedent on Fourth Amendment cases.
Law firmsMonitor new appellate rulings that cite their past wins.
Academic researchersBuild a corpus of federal district court opinions on patent eligibility.
Investigative journalistsTrack rulings from a particular circuit on FOIA disputes.

What it does

This Actor collects US court opinions from CourtListener's public search by keyword or as a live feed of recent filings, and returns each opinion as a flat row.

  • 🔍 Keyword search: Enter any legal phrase, case citation, or party name and pull every matching opinion.
  • 🆕 Latest opinions feed: Leave the search empty and the Actor returns the newest decisions filed on CourtListener.
  • ⚙️ Max items control: Stop the run after a chosen number of opinions, from a 10-item preview up to a million.

Results export to CSV, JSON, Excel, or XML, or straight from the API.

What you can do with CourtListener data

📈 Track judicial trends on a topic.

A legal tech startup enters 'generative AI' daily and feeds each opinion's judge and circuit into a dashboard showing which courts rule on AI copyright questions most often.

⚖️ Monitor new rulings that cite your firm's cases.

A litigation firm leaves the search blank and runs the Actor weekly, then filters the dataset for opinions that mention their past appellate wins by citation.

📚 Build a research dataset for empirical legal studies.

A law professor queries 'qualified immunity' across all circuits, collects five thousand opinions, and codes each one for outcome and reasoning in a statistical model.

🗞️ Investigate a judge's full published record.

A reporter searches for a newly appointed circuit judge's name, pulls every opinion they authored, and maps how often they side with the government in immigration appeals.

Troubleshooting

Why am I getting no results for my search query?

CourtListener's search may not return opinions that match your exact phrase. Try shorter keywords, remove quotes, or check if you misspelled a party name or citation. Leaving the query blank will always pull the newest opinions if no search term works.

Why is my run stuck or taking a very long time?

Large max item counts scan many pages. CourtListener's servers may throttle aggressive requests. Lower your max items or add a short delay between requests if your tooling allows it. The Actor respects public load and may pause naturally.

The data I scraped is missing a field I expected, like judge or citation.

Not every CourtListener opinion entry includes every metadata field. State court opinions, very old cases, or pro se filings sometimes lack a judge name or official citation. The Actor returns whatever data the public page contains.

I get an error about max items when I try to run the Actor.

Free tier runs are limited to a max of 10 items. If you set a higher number, the run may fail. Upgrade to a paid Apify plan to lift the cap and scrape up to 1,000,000 opinions per run.

Can I scrape by date range instead of keyword?

CourtListener's public search does not expose native date range filters in the URL this Actor reads. To approximate this, use search terms like a year or month name, or scrape the newest opinions feed and filter the resulting dataset locally.

FAQ

QuestionAnswer
Do I need a CourtListener API key to use this scraper?No. The Actor reads the public CourtListener opinion search pages, so no registration, API key, or OAuth flow is required.
How many opinions can I scrape in a single run?Free runs are capped at 10 items for a preview. Paid users can set the max items as high as 1,000,000 per run.
What data does the scraper return for each opinion?Every item includes the case name, court, judge, filing date, citation, docket number, and other metadata fields CourtListener provides in its public view.
Can I scrape opinions from a specific court or judge?Yes. Use the search query field and include the court name or judge's full name in quotes. The scraper passes your terms directly to CourtListener's own search engine.
How do I get the newest opinions without a search term?Leave the search query field empty. The Actor will scrape the most recent opinions filed across all jurisdictions on CourtListener.
Does this scraper work with RECAP docket documents?This Actor targets CourtListener's opinion search. It does not pull individual RECAP docket PDFs or filings. For docket data, a dedicated RECAP actor would be needed.

What export formats are available for the scraped data?You can export your dataset in JSON, CSV, Excel, XML, or RSS from the Apify platform once the run finishes.
Can I schedule this scraper to run automatically?Yes. Use Apify's scheduler to run the Actor daily, weekly, or on any cron schedule, so you always get fresh opinions without manual effort.
How do I cite scraped CourtListener opinions in my research?Each opinion comes with its official citation and URL when available. Check CourtListener's own citation guidelines to credit the source correctly in your work.
