matrx-legal
Legal data integrations for the Matrx ecosystem. Standalone-installable; first-class inside aidream.
Initial provider: CourtListener (REST API v4, bulk S3 dumps, webhooks). Designed to host additional sources (Westlaw, Lexis, Justia, CAP, Caselaw Access Project) behind a uniform interface.
What it does
- Async client for CourtListener REST API v4 with token-bucket throttling, cursor pagination, retry, and 429/
Retry-Afterhandling. - Pydantic models for every public response shape.
- Optional ORM persistence (matrx-orm) for cached opinions, dockets, courts, citations.
- Optional bulk ingest from CourtListener's free quarterly S3 dumps via Postgres
COPY. - Optional RAG indexing of opinion full-text (host injects the embedder).
- Optional FastAPI streaming endpoints (host wires them up).
- AI tool callables ready to register with
matrx-ai's tools registry.
Quick start
import asyncio
from matrx_legal.courtlistener import CourtListenerClient
async def main():
async with CourtListenerClient() as client:
async for hit in client.search(q="miranda v arizona", type="o", page_size=20):
print(hit.case_name, hit.absolute_url)
asyncio.run(main())
Set COURTLISTENER_API_TOKEN in your environment.
