ClassAction

ClassAction operates enjin (集団訴訟プラットフォーム enjin), a Japanese class-action / group-litigation platform that connects consumers who have suffered damages from the same party with registered attorneys to pursue collective lawsuits. Victims report their damages, registered lawyers volunteer to take on cases, and participants share legal costs and evidence so that even small-value claimants can afford to litigate. The service launched in May 2018 and is free for users. This is a consumer-facing legal-tech website with no public developer API, documentation, or SDKs; it was added to the API Evangelist network as a 500 Global portfolio lead.

ClassAction is profiled on the APIs.io network. Tagged areas include Company, Legal, Legal Tech, Class Action, and Litigation.

ClassAction’s developer surface includes engineering blog and 5 more developer resources.
