Vendor Profile

WeatherAPI.com is a high-reliability weather and geolocation API trusted by 850,000+ developers. It gives AI agents instant access to real-time conditions, hourly/daily/15-min forecasts up to 300 days ahead, historical weather from 2010, marine weather, air quality (AQI), pollen counts, solar irradiance, astronomy, sports data, IP lookup, and timezone info — all in clean JSON or XML with ~200ms average latency. Ideal for agents that need to make weather-aware decisions, enrich location context, or automate any workflow dependent on environmental conditions.
