One Call API®, endpoint version 2.5 Deprecated

As opposed to our subscriptions with a fixed monthly cost, One Call API has its own separate subscription with a variable cost, in proportion to your actual use of the API. Apart from additional functionality (47+ years years of historical data are now available via this API), users can configure and limit their usage to ensure that they don’t make more requests than expected. Read more about this subscription plan in the FAQ.

One Call API, endpoint version 4.0, is a unified weather intelligence API designed to give developers, digital products, and enterprise teams access to current weather, short-term forecasts, long-range daily outlooks, historical weather records, and official weather alerts through a single integration. Instead of combining multiple weather endpoints and datasets, users can request highly relevant weather information for any latitude and longitude from one product family built around a consistent response structure.

One Call API, endpoint version 4.0, contains 6 endpoints and provides access to various data:

• Current weather conditions
• Minute-by-minute forecast data for the next 60 minutes
• 15-minute forecast data for the next 48 hours
• Hourly weather timelines spanning 47+ years years of history and 48 hours of forecast
• Daily weather timelines spanning 47+ years years of history and up to 1.5 years ahead
• Detailed weather alert information from national agencies

One Call API, endpoint version 4.0, is based on the proprietary OWHL ™ OpenWeather Hyper-Local Forecasting Model and is updated every 10 minutes. Thus, to receive the most accurate and up-to-date weather data, we recommend you request One Call API, endpoint version 4.0, every 10 minutes.
