country_info
Country facts
Any country's essentials: capital, population, GDP and GDP per capita (World Bank), currencies, languages, calling code, internet TLD, time zones, driving side, borders, flag. Static facts from the world-countries dataset (no rate limits) plus the latest World Bank population and GDP figures. Price: free. Errors: returns isError with a message for invalid input or an upstream failure (not charged).

geocode
Geocode / reverse geocode
Place name or address → coordinates (with city, state, country, postcode), or lat,lon → the nearest address. Up to 10 candidates. OpenStreetMap data via Photon. Returns OSM links so results can be checked. When to use: To turn names into coordinates; weather and sun_moon accept place names directly. Price: $0.001 per call (10 free/day; after that a payment-required result lists x402 options). Errors: returns isError with a message for invalid input or an upstream failure (not charged).

time_convert
Time zones + date math
Current time in any time zones, convert a time between zones (DST-correct), and date arithmetic: add/subtract durations, days between dates, weekday, ISO week, Unix time. Computed locally from the IANA time-zone database — no rate limits, exact. Zones are IANA names (America/New_York, Asia/Tokyo, UTC). Price: free.

weather
Weather now + forecast
Current weather and hourly/daily forecast for any place name or lat,lon: temperature, feels-like, wind, gusts, rain, cloud, humidity, UV — up to 9 days. Forecast from the Norwegian Meteorological Institute (MET Norway), the same model data yr.no uses, worldwide. Place names are geocoded with OpenStreetMap. Times are UTC plus local time when tz is given (IANA, e.g. Australia/Sydney). Price: $0.001 per call (10 free/day; after that a payment-required result lists x402 options). Errors: returns isError with a message for invalid input or an upstream failure (not charged).
