Bilibili Scraper: Videos, Danmaku & Comments (B站)

Search Bilibili (哔哩哔哩, B站) videos by keyword or fetch them by URL and get clean JSON: title, description, tags, uploader, publish time, duration and full stats (views, likes, coins, favorites, shares, danmaku and comment counts). Optionally add the danmaku (弹幕) bullet comments with their position in the video, and the hot comment threads.

• No login, no cookies. Only public data. Your account is never involved.
• Cheap. $2 per 1,000 videos, danmaku $3 per 1,000 videos (all danmaku of a video for one price).
• Fast. Runs without proxies by default; results start in seconds.

Limits

• Without login Bilibili only shows the top hot comment threads of a video (about 3 root comments plus their replies). Full comment sections are not available.
• The danmaku endpoint returns the most recent part of the danmaku pool (usually up to a few thousand per video), not the full history.
• Search returns at most 1,000 results (50 pages) per keyword, like the Bilibili website.
• Only public data is collected. No private, members-only or deleted content.
