What is bilibili-api-collect?

This project is an archived copy of a community-maintained document that catalogs the behind-the-scenes APIs (the communication channels software uses to talk to servers) of Bilibili, one of China's largest video and entertainment platforms. Think of it as a detailed map of how Bilibili's website, mobile app, and TV app actually work under the hood. The original repository was archived by its creator, and this fork preserves that work so it stays accessible. The documentation covers an enormous range of features: logging in, searching for videos, fetching video stream URLs, reading and posting comments, retrieving live-stream data, pulling danmaku (the scrolling bullet comments Bilibili is famous for), browsing user profiles, interacting with the manga platform, and many more. Researchers figured out how these endpoints work through methods like monitoring network traffic, reverse-engineering the apps, and controlled experimentation, then wrote up their findings in plain Markdown documents organized by feature area. Someone building an unofficial Bilibili client, a browser extension, a data analysis tool, or a chatbot that interacts with the platform would use this as their reference guide. For example, if you wanted to build a custom video player that pulls Bilibili streams, or a tool that tracks live-stream statistics, this documentation tells you which endpoints to call and what the responses look like. A few important caveats: the project is explicitly for learning and testing only, not commercial use. The maintainers repeatedly warn against abuse and remind contributors to strip out sensitive data like session cookies before sharing anything. The documentation is also a work in progress, with many sections still incomplete or outdated, and the project could be taken down at any time given its unofficial nature. The master branch contains the unmodified sync of the original archive, while the main branch adds some preserved image resources.
