❓ FAQ

Do I need a Bilibili account, cookies or a proxy?

No. The Actor reads what bilibili.com shows any visitor who is not logged in. If Bilibili answers with a risk-control check, the request is retried on a fresh visitor session and, if needed, through Apify Proxy — by itself.

Does it work with Chinese keywords?

Yes. Search accepts Chinese, English or any other text: 原神, iphone 17, minecraft. Titles and descriptions come back as published, usually in Chinese.

How many comments can I get?

Bilibili shows a visitor who is not logged in only the first few top-level comments of a video. The Actor returns those comments together with all of their replies, so a popular video still gives dozens to hundreds of rows. Danmaku have no such limit.

Is it legal to scrape Bilibili?

The Actor reads only public pages without logging in. User names and comments are personal data under laws like the GDPR and PIPL — have a lawful reason to process them.

Can I get only new rows on a schedule?

Yes. Give Monitoring mode a name and schedule the Actor: every run returns only videos, danmaku or comments not delivered before under that name.
