• Multi-part aware: resolves every part (P1, P2, ...) of a video and tags each danmaku with its part index and part title.

• Free tier: 10 lifetime preview runs, up to 100 danmaku per run. No credit card required.

How to Scrape Bilibili Danmaku

Paste one or more videos into videoUrls and run. Each video can be a full URL, a BV id, or an av number.

Basic: one video

{
    "videoUrls": ["https://www.bilibili.com/video/BV1DYjA6KEJ7"]
}

Several videos at once

{
    "videoUrls": ["BV1DYjA6KEJ7", "av116770799295304", "https://www.bilibili.com/video/BV16D7T6AEP7"]
}

Cap the danmaku per video

{
    "videoUrls": ["BV1DYjA6KEJ7"],
    "maxDanmaku": 500
}

Only a time window (e.g. the first two minutes)

{
    "videoUrls": ["BV1DYjA6KEJ7"],
    "startSec": 0,
    "endSec": 120
}

Input Parameters

Parameter	Type	Default	Description
videoUrls	string[]	["https://www.bilibili.com/video/BV1DYjA6KEJ7"]	One or more Bilibili videos. Accepts a full bilibili.com/video/... URL, a BV id, or an av number.
maxDanmaku	integer	0	Max danmaku per video. 0 = all available. When capped, the most relevant (highest-weight) danmaku are kept, then restored to timeline order.
startSec	integer	0	Only danmaku at or after this many seconds into the video.
endSec	integer	0	Only danmaku at or before this many seconds into the video. 0 = no upper limit.

What Data Can You Extract from Bilibili Danmaku?

Every danmaku row includes:

• Content: the comment text (HTML entities decoded).
• Timeline: exact position in the video as seconds (videoTimeOffset) and as mm:ss (videoTimeFormatted).
• Appearance: display mode and a readable modeLabel (scroll, top, bottom, reverse, advanced, code), color as hex and decimal, and fontSize.
• Origin: send time as ISO date and epoch, an anonymized senderHash, the weight (Bilibili's relevance / quality score), the pool and poolLabel (normal, subtitle, special), and the danmakuId.
• Source video: videoBvid, videoAid, cid, partIndex, and partTitle.

Fields a danmaku does not provide are returned as null rather than dropped, so the column set stays stable across every row.

FAQ

What is danmaku (弹幕)? Danmaku are the user comments that scroll across a Bilibili video as it plays, anchored to a moment in the timeline. They are central to Bilibili's culture. This actor returns each individual danmaku message with its exact position, appearance, and send time.

How is this different from the Bilibili Video Scraper? The Bilibili Video Scraper returns the danmaku count per video as one engagement metric. This actor returns the individual danmaku messages themselves, one row each, with their timeline position and styling.

How many danmaku will I get per video? Bilibili serves a rolling display pool per video, typically up to a few thousand depending on the video's length. This actor returns that current pool. Use maxDanmaku to cap it, or startSec / endSec to slice a window.

Does it support multi-part videos? Yes. Every part (P1, P2, ...) is resolved, and each danmaku row carries its partIndex and partTitle.

Do I need a Bilibili account or cookies? No. Provide video URLs or BV ids and run. No account, cookie export, or QR login is involved.

How fresh is the data? Live. Every run fetches the current danmaku for each video at request time.

How do I export the data? JSON, CSV, Excel, XML, or HTML from the run's Storage tab, or via the Apify API.

What is a BV id, and where do I find it? The BV id is the unique code in a video's URL, for example BV1DYjA6KEJ7 in bilibili.com/video/BV1DYjA6KEJ7. Paste either the full URL, the BV id, or the av number into videoUrls.

Why is the sender shown as a hash? Bilibili identifies danmaku senders by an anonymized hash, not a username. The actor returns that hash as-is; it is not personally identifying on its own.

What's the free tier? 10 runs total per account, up to 100 danmaku each. No credit card required.

Is it legal to scrape Bilibili data? This actor extracts only publicly available data, nothing behind a login. You are responsible for complying with Bilibili's terms of service and applicable data-protection law (GDPR, CCPA, and China's PIPL).
