how to create a Kb articles search API using semantic query by a user

[rishabhkata]

I want to create an API that takes general search terms like we search in Portal using Ai Search and get knowledge articles based on generic query. Is there anything similar like this in servicenow that allows us to generate our custom api?

From where do you need to run this? AI search also searches for knowledge articles and if you want to run this from outside of ServiceNow, you will probably run into issues like not having access to the articles (or even worse: provide access to articles the users shouldn't be looking at).
