What are the available OpenAPI 3.0 servers with a full implementation except petstore example (https://petstore3.swagger.io/api/v3/openapi.json)?
It seems Marketo Swagger specifications are not updated to v3.0, may be v2.0.
I am developing an OpenAPI 3.0 client application, which has been successfully tested with the petstore example. But, I could not find any other server based on OpenAPI 3.0 to test my client app.
There're many OpenAPI 3.0 definitions on SwaggerHub:
Also check out this OpenAPI directory:
You can also convert OpenAPI 2.0 definitions to 3.0 - everything that can be expressed in OpenAPI 2.0 is supported in OpenAPI 3.0 as well.
