What European Commission JSON Validator is

European Commission JSON Validator checks JSON content against one or more JSON schemas. The generic validator accepts schemas supplied by users, and validation is available through a web interface, REST API, SOAP API, or command-line tool. Validators can define multiple validation types and domains, use local or remote schemas, and customize user-facing text. For each validation type, a user-provided schema can be required, optional, or disabled. Standalone validators can also be integrated into conformance test cases as validation steps. The service is free at no cost plan. Standalone use requires no registration and does not record inputs or produced reports. It can run locally or on-premises with Docker, or be used as a public service hosted on the Test Bed. The shared service is available over the Internet; an on-premises installation is suggested when that access is unacceptable or private resources are needed. Source code is available on GitHub, with stable and daily releases published on Docker Hub.
