How to let ChatGPT read Xiaohongshu (RedNote)
Xiaohongshu's open platform offers sign-in only, with no API for public notes. To let ChatGPT read them, add SocialToAI's MCP server as an app in ChatGPT: paste one address, sign in and press Allow. ChatGPT can then read its notes, comments, accounts and trends, from 12 credits a call. Failed calls are free.
Xiaohongshu's own API
Xiaohongshu's open platform currently offers login only: after the app passes review, it can read the basic profile (nickname, avatar) of users who authorise it. No API for reading public notes or comments is documented.
