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

Scrape public data from Bilibili (哔哩哔哩, B站), China's largest video community, with no login, no cookie and no API key. Search videos by keyword, get full video details, export comments and replies, pull the popular / trending board and creator profiles, and summarise a video's danmaku (弹幕) bullet comments into one row.

$2 per 1,000 rows. It runs on Apify's datacenter proxy by default and switches to residential automatically only if Bilibili blocks the run.

Pricing (pay per event)

Event	Price
Run start	$0.001 per run
Row (video, comment, reply or creator)	$0.002 ($2 per 1,000)
Danmaku summary (one row per video, only with includeDanmaku)	$0.01

Error rows are free. Set maxChargeUsd (default $5) and the run stops cleanly before it goes over; rows already delivered are kept.

Example costs: 100 search results = $0.20. 10 videos × 50 comments = 510 rows ≈ $1.02. Danmaku summaries for 50 videos = $0.50.

Compact output for AI agents

Set Output format to compact and the run still pushes the same rows to the dataset at the same price — nothing about billing changes. It additionally writes OUTPUT_COMPACT to the run's key-value store: a lossless columnar JSON encoding of the same rows (one column-name header plus one array per row, instead of repeating every key name on every row), which is cheaper to hand to an LLM than the plain dataset JSON.

Measured on a real 406-row export of this actor's comment/reply rows (see benchmarks/compact-output/ in this repo for methodology and all 5 actors' numbers):

Tokenizer	Pretty JSON	Minified JSON	Compact	vs Pretty	vs Minified
cl100k_base (GPT-4/3.5)	74,310	59,673	45,538	38.7% smaller	23.7% smaller
o200k_base (GPT-4o)	67,672	53,034	39,320	41.9% smaller	25.9% smaller

Decoding it back to the normal row objects is five lines of Python:

def decode_columnar(payload):
    cols, marker = payload["columns"], payload["missing"]
    return [{c: v for c, v in zip(cols, row) if v != marker}
            for row in payload["rows"]]

Good to know

• Public data only. The actor never logs in. Comment rows carry only the public nickname and mid; no avatars or other personal fields.
• Subtitles: Bilibili only serves subtitle and AI-subtitle text to logged-in users, so this actor reports hasSubtitles (whether tracks exist) and does not download the text.
• Creator upload lists (space pages) are blocked by Bilibili's risk control without login. To find a creator's videos, use search with their name.
• Search depth: Bilibili caps one keyword at about 1,000 results. Use date windows or more specific keywords to go further.
• Danmaku: Bilibili keeps a capped pool per video. danmakuPoolCapped tells you when the summary covers part of the total.
• Reliability: a self-test runs every day against live Bilibili endpoints, so breakages get spotted and fixed fast. If Bilibili blocks every request in a run, the run is marked failed instead of ending green with 0 rows, so your schedule alerts fire.

FAQ

Is there an official Bilibili API? Not for international developers. This actor uses the same public endpoints the website uses.

English or Chinese keywords? Bilibili indexes Chinese text. Searching 耐克 returns many more videos than "Nike".

How do I schedule it? Save your input as a Task in Apify Console, then add a Schedule (for example 0 8 * * * for daily at 8 AM).
