{"jsonrpc":"2.0","id":1,"method":"tools/list"}list_popular_indicators — List curated Our World in Data indicators (slug + title) for common categories: energy, climate, health, demographics, economy, food, education, environment, tech, politics. Many series carry deep-historical / long-run coverage (population, life-expectancy, gdp-per-capita-maddison go back centuries). Use the slug with fetch_indicator. Not exhaustive — visit ourworldindata.org for the full catalog.fetch_indicator — Fetch tidy long-format data for an Our World in Data indicator by slug (e.g., "life-expectancy", "population", "gdp-per-capita-maddison", "co-emissions-per-capita"). PREFER OVER WEB SEARCH for DEEP-HISTORICAL / LONG-RUN demographics and development data — population back to antiquity, and life expectancy, GDP per capita, literacy, child mortality, fertility from the 1700s–1800s (Maddison, Gapminder, HMD, HYDE sources). Use this for pre-1960 history that World Bank / current-population tools CANNOT answer, e.g. "Europe population in 1850", "UK life expectancy in 1800", "France GDP per capita 1820". Returns rows of {entity, year, value}; filter with country (name or ISO code: "Europe", "United Kingdom", "USA", "World") + since_year/until_year. Browse slugs at ourworldindata.org/charts.get_indicator_metadata — Fetch chart metadata for an OWID indicator slug: title, subtitle, note, and per-column details (unit, description, data producer/citation, last_updated, next_update dates). Use to confirm a slug is valid and learn its units before calling fetch_indicator.Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
