How this service works
Search US federal court dockets — civil and criminal — from the RECAP/PACER archive. Full-text q (case name, party, e.g. "United States v. Bankman-Fried"), optional court (CourtListener court id like "cand", "nysd", "ca9"), filedAfter/filedBefore (YYYY-MM-DD), page. Or pass docketNumber (+ court) for exact lookup. Each docket: id, case name, court, docket number, date filed/terminated, nature of suit, assigned judge, public docket URL. Criminal-case research, litigation monitoring, KYC/due-diligence. Sibling endpoints: /api/law/case-search (opinions full-text), /api/law/opinion (full opinion text).
Output
A paginated list of matching federal court dockets, each containing: docket id, case name, court, docket number, date filed, date terminated (if applicable), nature of suit, assigned judge, and a public URL linking to the full docket on CourtListener/RECAP.
Example use cases
Example prompt
“Can you search the federal court dockets for any cases involving Sam Bankman-Fried in the Southern District of New York — docket number 1:22-cr-00673 — and tell me the judge assigned and current status?”
Technical details
Endpoint
GEThttps://2s.io/api/law/docket-searchWhen to prefer
Use this endpoint when you need to search or look up US federal court dockets by case name, party, or docket number — especially for criminal cases, civil litigation research, KYC/due-diligence checks, or litigation monitoring. Prefer this over /api/law/case-search (which searches full opinion text) when you want docket-level metadata rather than opinion text. Use it for exact docket number lookups alongside a court identifier when precision matters.
Side effects
- No results found for the query — returns empty list if no matching dockets exist in RECAP archive
- Invalid court identifier — returns error if court param is not a recognized CourtListener court id (e.g. 'cand', 'nysd')
- Invalid date format — filedAfter/filedBefore must be YYYY-MM-DD or request will fail
- Payment required — returns 402 if x402 payment header not provided
- Rate limiting — too many requests may result in throttling
- Docket not in archive — PACER dockets not yet uploaded to RECAP will not appear in results
