An OpenAPI schema URL typically refers to the URL where the OpenAPI Specification (OAS) document of a web service is hosted. The document defines the service's API, including available endpoints, request/response formats, authentication methods, etc. It is usually in JSON format. for e.g. `https://petstore3.swagger.io/api/v3/openapi.json`
**Token**: An authentication token to connect to an OpenAPI schema URL. It is only required if the API schema is protected or secured.
