The OpenAPI Initiative OAI a consortium of forward-looking industry experts who focus on standardizing how APIs are categorized and described released the OpenAPI Specification 3.1.0 in February. This new version introduces better support for webhooks and adds 100 compatibility with the latest draft 2020-12 of JSON Schema.
Complete information on the OpenAPI Specification OAS is available for immediate access here httpsspec.openapis.orgoasv3.1.0 It includes Definitions Specifications including Schema Objects and much more.
Also the OAI sponsored the creation of new documentation to make it easier to understand the structure of the specification and its benefits. It is available here httpsoai.github.ioDocumentation. It is intended for HTTP-based API designers and writers wishing to benefit from having their API formalized in an OpenAPI Description document.
The OAS is the industry standard for describing modern APIs. It defines a standard and programming language-agnostic interface description for HTTP APIs which allows both humans and computers to discover and understand the capabilities of a service without requiring access to source code additional documentation or inspection of network traffic.
