In plain English

This repository, which previously collected documentation about Bilibili's unofficial API endpoints, has been permanently closed. The maintainer received a legal warning letter from lawyers acting on behalf of Bilibili (the Chinese video-sharing platform) in January 2026, stating that the project systematically collected and publicly distributed details about Bilibili's non-public API interfaces, including their calling logic, parameter structures, access controls, and authentication mechanisms. The repository has since been shut down and its documentation and source code deleted.
