get_dataset_inforead-onlyDescribes the Penguin Statistics drop data: what its numbers mean (times, quantity, drop rate, sanity per item, window), the game servers with their time zones and how fresh the data of each is, the caveats, the license and how to credit it. Call it when unsure how to read or cite the numbers.
get_item_drop_ratesread-onlyWhere to farm an item: ranks every stage of a game server that drops it, with sanity per item, drop rate (items per run), runs (times) and quantity. Use it for any question about where to get an item, its best or most efficient stage, or which of several stages to run for it: one call ranks every stage, so don't look stages up one by one with get_stage_drops (only a named stage left out of the top
get_stage_dropsread-onlyWhat one stage drops on a game server: each item with drop rate (items per run), sanity per item, runs (times) and quantity, highest rate first, then the items it no longer drops; with the sanity cost of the stage and whether it is open now. For questions about a given stage. To find where to farm an item, call get_item_drop_rates instead: one call ranks every stage that drops it. Takes the stage
list_eventsread-onlyLists the events (limited-time activities) of a game server: status now (open, upcoming or closed), open and close times, whether a rerun. By default the open and upcoming events with their stage IDs (for get_stage_drops), or the latest 3 if there are none; open_only=false lists every event, latest first, with stage counts only. The main story and the permanent side stories are not events.
search_itemsread-onlyFinds items (materials, battle records, chips, furniture, event items) by name in any language (zh, en, ja, ko), by alias or nickname (土块, 狗粮), by pinyin (guyuanyan) or by item ID, and returns their item IDs (get_item_drop_rates takes a name too; search first when unsure which item is meant) and names in every language. Best matches first: exact before prefix before substring, names before aliases
search_stagesread-onlyFinds stages by code (1-7, S2-12, YW-4; full-width characters work too), by stage ID (main_01-07), or by the name or ID of their zone (第十章, Under Tides), and returns their stage IDs (for get_stage_drops; to find the stages that drop an item, use get_item_drop_rates) with their zone, sanity cost and whether they are open on the server now. Codes are not unique: the standard and tough versions of a
