courtlistener-api-client 0.0.4

Official Python SDK for the CourtListener API

CourtListener API Client

A Python client for the CourtListener API, providing access to millions of legal opinions, dockets, judges, and more from Free Law Project.

Installation

pip install courtlistener-api-client

Authentication

You'll need a CourtListener API token. You can get one by creating an account and generating a token in your profile settings.

Set it as an environment variable:

export COURTLISTENER_API_TOKEN="your-token-here"

Or pass it directly to the client:

from courtlistener import CourtListener

client = CourtListener(api_token="your-token-here")

Quickstart

from courtlistener import CourtListener

client = CourtListener()

# Get a specific opinion by ID
opinion = client.opinions.get(1)

# Search for opinions
response = client.opinions.list(cluster__case_name="Miranda")

# Access results from the current page
for opinion in response.results:
    print(opinion)

# Check the total count of matching results
print(response.count)

# Iterate through all results across pages
response = client.dockets.list(court="scotus")
for docket in response:
    print(docket)

Pagination

List queries return a ResourceIterator that handles pagination automatically:

results = client.dockets.list(court="scotus")

# Iterate through all results across all pages
for docket in results:
    print(docket)

# Or navigate pages manually
results = client.dockets.list(court="scotus")
print(results.results)   # current page results

if results.has_next():
    results.next()
    print(results.results)  # next page results
