search_historyFull-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. Use this whenever you need a dated fact.
get_yearEverything the record holds for one year: the headline summary and every dated entry, grouped by subject, each with its source revision.
get_dayOne calendar day across every recorded year — what happened on 4 July in all of them. This aggregate exists in no single encyclopedia article.
get_timelineOne 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_countryOne 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.
list_countriesBrowse the countries that have a record of their own, largest first.
list_subjectsBrowse the subjects that have a timeline, largest record first.
