Bilibili Scraper – video metadata, uploader profiles & danmaku

Introduction

Extract public Bilibili (B站) data with plain HTTP: no browser and no login. Each result is one dataset row, and the type field tells you what kind of result it is.

Supported data

• ✅ Video metadata: title, description, uploader, publish time, duration, views, likes, coins, favorites, shares, tags, and multi-part (分P) info
• ✅ Uploader (UP主) profiles: followers and basic stats
• ✅ Danmaku: bullet comments with in-video timestamps, from the public endpoint. This is a partial sample, not the full danmaku history.
• ⚠️ Comments (limited): guests get only 3–4 top-level comments per video. Replies can be fetched.
• ⚠️ Subtitles (limited): most videos require login, so subtitles are usually unavailable. When none are returned, a free notice row is written instead.

Use cases

• UP主 / KOL analysis: compare reach and engagement before sponsorships
• Trend and content research: views, tags and danmaku timing
• AI agents and LLM tools: structured Bilibili metadata as context
• Brand monitoring: danmaku reactions on product videos

B站数据工具：视频信息、UP主资料、弹幕

简介

纯 HTTP 抓取 B站公开数据，不开浏览器，也不登录。每条结果一行，用 type 字段区分类型。

支持的数据类型

• ✅ 视频信息：标题、简介、UP主、发布时间、时长、播放、点赞、投币、收藏、分享、标签、分P信息
• ✅ UP主资料：粉丝数和基础数据
• ✅ 弹幕：带视频内时间点，来自公开接口。只是部分样本，不是全部历史弹幕。
• ⚠️ 评论（有限支持）：未登录时每个视频只返回 3–4 条一级评论，楼中楼可以抓到。
• ⚠️ 字幕（有限支持）：大多数视频的字幕需要登录，通常拿不到。拿不到时写一条不扣费的 notice 记录。

用例

• UP主/KOL 分析：投放合作前比较影响力和互动数据
• 趋势和内容研究：播放量、标签、弹幕出现的时间点
• AI 智能体、大模型工具：提供结构化的 B站元数据作为上下文
• 品牌监测：产品视频下的弹幕反应
