Info Object in OpenAPI

The document’s info object contains information about the document, including fields like title, version, and description that help to identify the purpose and owner of the document.

Example:

openapi: 3.1.0
info:
  title: The Speakeasy Bar
  version: 1.0.0
  summary: A bar that serves drinks
  description: A secret underground bar that serves drinks to those in the know.
  contact:
    name: Speakeasy Support
    url: https://support.speakeasy.bar
    email: support@speakeasy.bar
  license:
    name: Apache 2.0
    url: https://www.apache.org/licenses/LICENSE-2.0.html
  termsOfService: https://speakeasy.bar/terms

Field	Type	Required	Description
`title`	String	✅	A name for the API contained within the document.
`version`	String	✅	The version of this OpenAPI document, not the version of the API or the OpenAPI Specification used. This is recommended to be a Semantic Version (opens in a new tab).
`summary`	String		(Available in OpenAPI 3.1.x ONLY) A short sentence summarizing the API contained with the document.
`description`	String		A longer description of the API contained within the document. This may contain CommonMark syntax (opens in a new tab) to provide a rich description.
`contact`	Contact Object		Contact information for the maintainer of the API. Note: Currently not supported by Speakeasy tooling.
`license`	License Object		The license the API is made available under.
`termsOfService`	String		A URL to the terms of service for the API.
`x-*`	Extensions		Any number of extension fields can be added to the info object that can be used by tooling and vendors to add additional metadata and functionality to the OpenAPI Specification.

The above order of fields is recommended (but is not required by the OpenAPI specification) as it puts the most important information first and allows the reader to get a quick overview of the document and API.
