penguin-stats-api
Query Arknights (明日方舟) item drop rates from Penguin Statistics (企鹅物流数据统计, penguin-stats.io), the crowdsourced drop statistics of the CN, US, JP and KR game servers. Use when the user asks where to farm (刷图) an item, which stage drops a material best, the drop rate (掉率) or sanity (理智) cost per item of a stage, what a stage drops or which events are open, or when writing code that calls the Penguin Statistics API or its MCP server. Covers which endpoint or MCP tool to use, how to compute drop rates (quantity / times), time windows, servers, rate limits and etiquette, and how to credit the data (CC BY-NC 4.0).
