1. Is this request related to a challenge you're experiencing? Tell me about your story.

I want to develop based on Dify, but I can't simply get the app information through AppApi, checking the source code, I found that: you have to log in to your account or set the ADMIN_API_KEY to call AppApi.

Requirement: like ChatApi can be authenticated by api_key and then get the basic information of the app.

Oh, we can use the service_api AppInfoApi, but it returns too little information. Maybe we should return more information, at least like app_detail_kernel_fields.

Sounds reasonable to me.
