Semantic Kernel plugin with API manifest file

[ktjosh]

Hello, I am trying to create a plugin using Api manifest file, and I am having difficulty finding good documentation about it.
one particulate question is regarding the schema of Api manifest file.

I see the application description URL is place where a yaml file is provided with Api description and all the other details, however, If I do not have such yaml file uploaded on a server, then can I create plugin using Api manifest ?

Further question is, does it mean the plugins uploaded on open ai have the capabilities to be used in Api manifest, or i can use my personal open to public services as a plugin in the semantic kernel.

Thank you.

Hello @ktjosh are you using SK Python or C#? Python supports the v3+ OpenApi spec and I believe that C# supports 2.0+ and 3.0+. When creating a plugin from an OpenApi spec, you will need to provide it the spec as either yaml or json so that we can parse it and create the required kernel functions / plugin.

Further question is, does it mean the plugins uploaded on open ai have the capabilities to be used in Api manifest, or i can use my personal open to public services as a plugin in the semantic kernel.

Are you referring to an OpenAI plugin? Those plugins were deprecated by OpenAI are no longer supported in SK.

By your question is sounds like you're using SK C#, but please correct me if I am wrong. Have you seen this OpenApi plugin sample?
