Tools as reported by the server

• search_history
  Full-text search across every dated entry in the historical record, plus the subjects that match. Each entry is a sentence quoted verbatim from a numbered English Wikipedia revision and carries that revision id, so an answer built on it can cite a source that will still say the same thing next year.
• get_year
  Everything the record holds for one year: the headline summary and every dated entry, grouped by subject, each with its source revision.
• get_day
  One calendar day across every recorded year — what happened on 4 July in all of them. This aggregate exists in no single encyclopedia article.
• get_timeline
  One subject's whole record in date order: every dated entry across all years in which Wikipedia's editors linked to it, with its Wikidata id for joining to other datasets.
• get_country
  One country's dated record, century by century, harvested from the per-country year articles English Wikipedia writes separately ('1969 in Japan') and never indexes together. Use this when the question is about a nation rather than a year or a subject.
• get_year_facts
  What a year (1800-2025) looked like in numbers, from outside sources rather than encyclopedia prose: world population, U.S. CPI and what a dollar then is worth now, average U.S. prices (gas, eggs, bread, milk, houses, income, minimum wage), who led the major powers, and the Billboard Hot 100 No. 1 s
• get_leaders
  Who led a country (or every country) in a year, 1800-2025: heads of state, heads of government and ruling-party leaders, in the order they held the post. Each name is quoted from Wikipedia's list of state leaders (revision id given) and kept only where the person's Wikidata record holds the same pos
• get_number_one_song
  The Billboard Hot 100 No. 1 single on a given date (1958-08-04 onward): the first chart issue dated on or after that day, quoted from a cited Wikipedia revision.
• convert_dollars
  Inflation-adjust U.S. dollars between years with the BLS CPI-U (1913 onward). Omit to_year for the latest published month.
• list_countries
  Browse the countries that have a record of their own, largest first.
• list_subjects
  Browse the subjects that have a timeline, largest record first.
