Polyarchy Statistics (統計参照DB)

ClaudeCommunityby Polyarchy

Polyarchy Statistics is a read-only reference service for exact values of Japanese official statistics and international statistics. Coverage includes GDP and quarterly estimates, prices, wages, labor, public finance, flow of funds, population, corporate statistics by industry and size, and country comparisons from the IMF, OECD and World Bank. It has two layers. Discovery tools (list_datasets, find_statistics, list_sources) find which series exist. Reference tools (lookup_statistic, lookup_panel) return the value for an exact series and period. What it returns: the value as published, as a string, with unit, the survey and table it comes from, the source URL, the retrieval date and the redistribution terms of the source. What it does not do: it does not convert, round, seasonally adjust, interpolate or splice values. If the exact series and period are not in the database, it returns found=false with the reason instead of a nearby year or a similar indicator. Some series are guide-only: the service explains where to read the value in the original source and holds no value itself. Values belong to the publishing agencies; the service does not guarantee them, so check the original source. This service uses the API of e-Stat (the portal site of official statistics of Japan), but its content is not guaranteed by the government. Tool descriptions and results are in Japanese. Tool arguments are logged for 30 days for quality improvement; conversation content is not collected. 日本の公的統計と国際機関統計の値を、公表どおりの文字列で厳密に参照する読み取り専用のサービスです。該当が無ければ found=false と理由を返し、近い年や隣の指標では埋めません。各値に出典（統計名・表・URL・取得日）と再配布条件が付きます。
