Does Weibo have an API?
Not for public posts: Weibo's API returns only the authorised user's own posts. SocialToAI reads its publicly visible posts, comments, accounts and trends without a Weibo developer account: 8 interfaces from 2 credits a call (≈ $0.004–$0.0067), and failed calls are free. Official facts checked 2026-10-17.
The short answer
Not for public posts: Weibo's API returns only the authorised user's own posts.
What the official API allows
Weibo's open platform API requires OAuth, and its post-reading endpoints return only the authorised user's own posts; advanced endpoints require a separate application.

Reading Weibo's public data with SocialToAI
SocialToAI is an API and MCP server for publicly visible content and account information. You need no Weibo account and no app review: one SocialToAI key, or signing in from Claude, ChatGPT, Claude Code, Cursor and Codex. Each call costs a fixed number of credits, and a failed call costs nothing.
