Instagram mobile apps api

i need your help. does someone here know what api which using by instagram mobile apps instagram?
the assumption is i make my own crawler plugin for instagram hashtag and post by api i got from web inspect element and instagram graphql such as https://www.instagram.com/explore/tags/${hashtagName}/ and https://www.instagram.com/api/v1/tags/web_info/?tag_name=${hashtagName},
but the hashtag isn’t complete, only get 20-40 post.

but when i simulate by mobile apps to try the hashtag search, it will get all post, i tried so hard using frida for ssl pinning but that’s useless to see the api. so i need y’all help for the api which use by the mobile apps. thank you! 😀
