Bilibili Scraper: Videos, Comments, Danmaku (弹幕) & Native Subtitles

Scrape Bilibili (哔哩哔哩 / B站) by keyword or URL, video search, video details, comments, UP主 (creator) profiles, danmaku (弹幕 bullet-comments), native subtitle transcripts, and trending. No cookies. No login. Give it a keyword or a plain video link and it returns clean, structured JSON, and you pay only for the results you get back.

This is the only Bilibili scraper on Apify that extracts both raw danmaku bullets and Bilibili's native subtitle track as a transcript, instantly, at any video length, with no cookie and no audio re-transcription.

What is Bilibili?

Bilibili (哔哩哔哩, "B站") is one of China's largest video platforms, 300M+ monthly users, huge in anime, gaming, tech, and education. Its signature feature is danmaku (弹幕): real-time comments that scroll across the video as it plays. Bilibili also has its own engagement metrics, coins (投币) and favorites (收藏) on top of the usual views, likes, and replies, all of which this scraper captures.

Is there an official Bilibili API?

There is no public, international Bilibili API. Bilibili's developer platform requires Chinese phone verification and is heavily rate-limited, and most public data sits behind WBI request signing. This actor is the practical Bilibili API alternative: it handles the signing and returns structured JSON with zero authentication, no cookie, no account, no proxy setup.

What data can you extract from Bilibili?

Pick a mode with the What to scrape dropdown. Each mode is billed as its own event, and you only pay for results returned.

Mode	Input	Returns
Keyword search → videos	keyword(s)	Videos: title, description, views, likes, coins, favorites, danmaku count, replies, author, duration, tags, category
Video detail	video URL / BV id	Full video: all engagement stats, owner, category, publish date, resolution, copyright (original/repost), and the full per-part (分P) breakdown (every episode's cid, title, duration)
Video comments	video URL / BV id	Comments: text, likes, reply count, author, timestamp, IP location (归属地), commenter level/VIP/verified, whether the UP主 liked/replied, and up to 3 free reply previews per comment
Danmaku (弹幕)	video URL / BV id	Bullet-comments: text, timestamp in the video, send time, mode, color
Transcript (native CC)	video URL / BV id	Native subtitle track parsed into timed segments + joined full text
UP主 profile	space URL / UID	Creator card: name, avatar, signature, level, fans, following, verification, VIP
UP主 videos	space URL / UID	Every video a creator posted: title, views, danmaku count, duration, category, cid, publish date
Trending	(none)	Trending videos (热门) or hot search terms (热搜)

Two things no other Bilibili scraper does well

• Raw danmaku (弹幕). Bilibili's scrolling bullet-comments are a data source no other platform has. Each call returns a full danmaku pool, often 1,000+ bullets, each with its exact timestamp in the video, so you can map audience reaction to the moment it happened. (Other actors only sell an aggregated "reaction profile"; this returns the raw bullets.)
• Native transcripts. When a video has a Bilibili subtitle track (including the auto-generated ai-zh one), this actor returns it directly as timed segments and full text, instantly, at any length. No audio download, no speech-to-text step, no 5-minute cap.

How do I scrape Bilibili? (3 steps)

1. Pick a mode in What to scrape (search, video detail, comments, danmaku, transcript, profile, UP主 videos, or trending).
2. Give it input, one or more keywords for search, or Bilibili video URLs / BV ids (e.g. BV1rpWjevEip) for the video modes, or a UP主 space URL / UID for profile and UP主 videos.
3. Run it and collect the structured results from the dataset (via the Console, the Apify API, or your language client).
