Why use UniCourt to search for cases in the District of Wyoming?

Searching for and collecting the court records you need for the District of Wyoming from the Public Access to Court Electronic Records, or PACER, can be expensive, difficult, and time-consuming.

UniCourt gathers court data for all of the new federal civil cases in the District of Wyoming every day and allows you to search through all the new case filings in our CrowdSourced Library™ for free. UniCourt also gives you real-time, bulk access to the entire PACER database of civil and criminal federal court data from the Wyoming District through our PACER API. Unlike UniCourt, PACER charges for every case search you make on their platform, even if the search terms you used do not produce any results. Further, PACER does not limit the cost of each case search you make, meaning you could be charged excessive fees for searches that return a mountain of results.

Unlike when you use PACER, which charges users to pay additional fees to download the same document multiple times, you can download documents from D. Wyo. in our CrowdSourced Library™ for free as many times as you want. Our free library is transparent, unlike PACER, which also charges additional document fees. PACER charges 10 cents per page and claims that these fees are capped at $3, but oftentimes the fees can be much higher for access to court transcripts.

In addition to the U.S. District Court for the District of Wyoming, UniCourt provides bulk access to all federal court records within Wyoming, such as cases filed in the U.S. Court of Appeals for the Tenth Circuit and the U.S. Bankruptcy Court for the District of Wyoming.

UniCourt’s industry-leading Legal Data APIs provide Enterprise users with on-demand, bulk access to structured data from Wyoming state and federal courts. UniCourt collects, organizes, standardizes, and normalizes court data from all federal courts and makes it easily accessible via our APIs as a part of our Legal Data as a Service (LDaaS) offerings for business development, competitive intelligence, litigation strategy, and docket management.
