Weibo Scraper

Scrape Weibo (微博), China's biggest microblog: search posts by keyword with a date range, the hot search board (微博热搜) and how it changes, trending posts, comments and replies, post details, user profiles and posts, and Black Cat (黑猫投诉) consumer complaints. $2 per 1,000 results. No login, no browser, no API key. Also known as 微博, Sina Weibo, Weibo crawler, Weibo API, Weibo hot search scraper.

Why this Actor

• Author follower counts in search rows, at no extra charge, so a brand search shows who has reach.
• Newest-first search that goes deep: up to 5,000 posts per query, with a date range in Beijing time.
• A user's latest ~10 posts without any cookie; more with your own cookie.
• Scheduled monitoring built in: delta mode returns only new posts and comments, follow-up comments re-read threads a day later, and hot search delta reports what rose or fell on the board.
• Free province rollup of where the posts came from.
• $2 per 1,000 results, light runs (256 MB), failed and filtered rows free. 10,000 posts cost $20.

What you get

• Posts: full text (long posts expanded at no extra charge), reposts, comments and likes counts, author (id, name, followers, verification, bio), images, video link, #topics#, the place it was posted from (发布于 广东), promoted-post flag, and the quoted original for reposts (repostOf).
• Hot search: rank, topic, hot value, label (热, 新, 沸), paid and pinned slots flagged. With hot_search_delta, each run reports new, rising, falling, steady or dropped, rank and hot-value change, minutes on the board and the running peak.
• Comments and replies: text, likes, replies, commenter id, name, followers and region.
• Profiles: followers, following, posts, verification, bio, location, sex, birthday (as shown), account age, company, sunshine credit, lifetime likes, comments and reposts.
• Black Cat complaints: company, title, text, what the consumer asks for, the problem, amount in dispute, progress (processing, replied, completed), date and link. The complainant is never included.
• Province rollup (free): share of posts per Chinese province or country, promoted posts and average sentiment.
• Sentiment (optional): lexicon-based polarity and score for Chinese and English.

Use cases

• Brand and campaign monitoring in China: search your brand (Nike also searches 耐克), schedule it with Delta mode and get only new posts and comments each day.
• Trend tracking: snapshot the hot search board every hour and see what is rising.
• Consumer research: comments under viral posts, complaints about a company on Black Cat.
• KOL tracking: profiles and current engagement of the posts you follow.
• Data for AI and analytics: stable JSON fields from the API, Make, Zapier or n8n.

Add includeComments, includeAuthorProfiles, geoRollup, sentimentAnalysis, adFilter or deltaMode to the post modes.

Scheduled monitoring

With deltaMode on, each run returns only posts, comments and complaints that no earlier run with the same deltaStateKey delivered (already-seen rows are free). A delta search reads posts minutes after they appear, before anyone replies, so add followUpComments: each post is remembered and a later run re-reads its comments once, 24 hours to 7 days after posting, and returns only the new ones (marked isFollowUp). For the hot search board, use the hot_search_delta mode on an hourly or daily schedule.

Search a period

searchDateFrom and searchDateTo take 2026-09-01 or 2026-09-01T08:00:00, in Beijing time (+08:00) unless you write an offset or Z: the same zone as every row's createdAtIso. The search starts at searchDateTo and walks back until it passes searchDateFrom or reaches maxResults; posts outside the window are dropped and not charged. The log says which posts the run reached.

FAQ

Do I need a Weibo account? No, except to read more than an account's latest ~10 posts (user_posts): Weibo shows deeper timelines only to signed-in sessions. For that, paste your Cookie request header from weibo.com into cookieString (F12 → Network → any weibo.com request → Request Headers). It is used only for those requests.

I already use another Weibo Actor. Do I need to change my input? Usually not: the input fields use the common names (mode, searchQuery, maxResults, postIds, userIds, includeComments, deltaMode...), so a saved input or an API call often works as it is.

Is there an official Weibo API? Weibo's developer API needs a Chinese business license and is heavily limited. This Actor reads the same public pages the Weibo website and app show to visitors.

How far back can a search go? Use searchDateFrom/searchDateTo. Weibo returns a sample of each period, not a complete archive, and the run stops at maxResults, your charge limit or the run timeout, whichever comes first.

How many comments per post? Up to 1,000 (maxComments), with replies when includeReplies is on.

How many Black Cat complaints? Black Cat shows visitors the 500 most recently active complaints per company and of the public feed.

What personal data is included? Only what Weibo shows publicly next to content: author and commenter public name, id, follower count and the region Weibo displays; profiles carry what the profile page shows publicly, sex and birthday included when the account shows them. Black Cat complainants are never included.

Is it legal? The Actor reads publicly available data without logging in (except user_posts with your own cookie). Check your local laws and Weibo's terms before using the data.
