What it can do
| Tool | What it says it does |
|---|---|
check_claim | Check one dated sentence against the record before stating it. Leaders, Billboard No. 1 singles and Nobel Prizes get a structured check that can return 'supported' or 'contradicted' with the source. Other claims are matched against the dated entries and the answer says where the record dates… |
convert_dollars | Inflation-adjust U.S. dollars between years with the BLS CPI-U (1913 onward). Omit to_year for the latest published month. |
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_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_disagreements | Where two sources slashyear checks against each other disagree: leaders' terms (Wikipedia lists vs Wikidata), birth and death dates (Wikipedia year articles vs Wikidata), Nobel Prizes (Nobel API vs Wikidata). Useful before trusting either source. |
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… |
get_nobel_prizes | Nobel laureates for a year (1901 on) or for a category across years, from the Nobel Prize API and kept only where Wikidata records the same prize in the same year. |
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. |
get_official_series | Official data series by year from the agencies that publish them, each cross-checked against a second copy: U.S. unemployment, federal funds rate, GDP, population, federal debt, Mauna Loa CO2, global temperature anomaly, Fed exchange rates. Omit series to list them. |
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_world_on_date | The world on one date in a single answer: the dated entries for that exact day, births and deaths that day, every state's office holders that year, the Billboard Hot 100 No. 1 in force, U.S. prices and CPI, world population, official series (unemployment, rates, GDP, debt, CO2, temperature)… |
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_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… |
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. |
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… |
In its maker's words
Sourced history by year: events, world leaders, prices and No. 1 songs, each with its source.
