Bilibili Scraper (B站): Video Search, Rankings & 弹幕 Analytics

Get Bilibili (哔哩哔哩 / B站) video data as JSON, CSV or Excel: keyword search that splits date ranges to get past Bilibili's 1,000-result cap, popular and category rankings with rank movement, and full stats with engagement rates on every row. It also tracks growth on videos you list, summarizes a creator's uploads and builds anonymous danmaku (弹幕) reaction curves. It does not collect comments or user profiles.

Use cases

• Brands and China-market agencies: find every video on your keyword and compare engagement.
• Campaign managers: run daily on sponsored videos to see views, likes and coins gained since the last check.
• Trend researchers: follow popular and ranking lists and see which videos are climbing.

Sample output

{
  "bvid": "BV1xrnz6gEVD",
  "title": "折1万次，会坏吗？iPhone Duo深度评测",
  "authorName": "影视飓风",
  "durationSeconds": 1492,
  "views": 5664762,
  "likes": 298768,
  "coins": 154677,
  "favorites": 58896,

  "viewsPerDay": 3068707
}

Price: 1,000 videos cost $1.50, plus $0.001 per run. Danmaku analytics add $3.00 per 1,000 videos, only when turned on. Hot searches and creator summaries are free.

Why this one

• Full coverage: Bilibili stops every search at 1,000 results. Full coverage splits the date range automatically, so a busy term like 咖啡 returns every video (about 600 a day), not just the first 1,000.
• Engagement metrics on every row: like, coin and favorite rates, total interaction rate, views per day and danmaku per minute, with no extra cost.
• Campaign tracker: list your sponsored videos, schedule a daily run, and get views, likes and coins gained since the last check.
• Rank movement: popular and ranking rows show the previous rank, places moved and new entries.
• You never pay for duplicates: Bilibili repeats videos across search pages; repeats are removed before saving.
• Honest failures: if Bilibili refuses requests, the run stops and is marked Failed instead of quietly returning less.

Add-ons

• Full video stats: search and creator lists carry basic counts; turn this on for coins, shares, the full description and complete metrics (one extra request per video, no extra charge).
• Danmaku analytics ($0.003 per video): one anonymous row per video: danmaku per minute, a minute-by-minute reaction curve, the peak moments and phrases repeated by at least 3 viewers. No sender data, no single messages, and phrases with @mentions, uids or long numbers are dropped.
• New videos only (monitor): remembers videos from earlier runs with the same key, so a scheduled search or list saves, and charges for, only new videos.

Dates accept 2026-10-01 or relative values like 7 days, 3 months, 1 year.

Limits

• Search depth without Full coverage: at most 50 pages (1,000 results) per term, usually 700–900 unique after repeats are removed.
• Danmaku: Bilibili's public track holds up to a pool limit per video (often a few thousand of the newest), so danmakuAnalyzed can be lower than danmakuTotalOnVideo.
• No comments or user profiles. The Actor collects video-level data and anonymous aggregates only.
• Rank movement and tracking start from the second run with the same list or Track key.
• If Bilibili refuses requests, the run pauses once, retries once, then stops and is marked Failed with a message, so a short result is never shown as complete. Try again later.

FAQ

Do I need a Bilibili account, cookie or proxy? No.

How fresh is the data? Live: every run reads Bilibili at that moment. Schedule the Actor for a daily or hourly series.

Can I search in English? Yes, but Chinese terms return far more. Add both as separate terms, e.g. Nike and 耐克.

Where do I find ids? Video: bilibili.com/video/BV1pGnn67EbB → BV1pGnn67EbB. Creator: space.bilibili.com/946974 → 946974. Full links and b23.tv short links work too.

Responsible use

The Actor reads public video pages and lists that anyone can see without logging in, identifies itself in its User-Agent, and keeps a gentle request rate. It collects no comments and no personal profiles; uploader names and ids appear only as the public author of each video, and danmaku are reported only as anonymous aggregates.
