Building professional OpenAPI specifications demands precision, but mastering JSON Schema is hard. This library eliminates that burden by providing production-ready schemas that encode industry standards and best practices. Reference them directly in your API specifications and focus on what matters: designing great APIs.

Led and maintained by a member of the JSON Schema Technical Steering Committee

Use this library to:

• Build production-grade OpenAPI specifications without writing schemas from scratch
• Skip the JSON Schema learning curve while maintaining expert-level quality
• Meet compliance and regulatory requirements with standards-based validation
• Establish a solid foundation for your organisation's API governance program

[!WARNING] This project is in its early stages with much more to come. We need your feedback to shape its future. Please share your thoughts and suggestions on what you would like to see.

[!NOTE] All schemas target JSON Schema 2020-12, the dialect used by OpenAPI v3.1 and later. Earlier JSON Schema dialects will be supported in the future.
