  + // OAS-defined Info Object
  + "info": {
  + "title": "Awesome service X - Production",
  + "version": "1.2.3",
  + // A URL to a page for terms of service.
  + "termsOfService": "https://sample.com/path/to/termsOfService",
  + // see: https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.0.2.md#contactObject
  + "contact": {
  + "name": "API Support",
  + // one of url and email is required.
  + "url": "https://sample.com/path/to/contact",
  + "email": "contact@sample.com"
  + },
  + // @see: https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.0.2.md#licenseObject
  + "license": {
  + "name": "License",
  + "url": "https://sample.com/path/to/license",
  + },
  + // Used as a URL to the endpoint icon.
  + "x-thumbnail": "https://sample.com/path/to/thumbnail.png",
  + // Theme of the endpoint.
  + "x-theme": "blue",
  + // An array of string values.
