Weather API Providers
High Resolution Weather data sales were discontinued in early 2025. Documentation for existing users is available High Resolution Weather (Meteomatics).
Forecast weather data
The returned forecast information accounts for 14 days ahead and includes information in regards to the cloudiness, temperature, precipitation, humidity, wind and much more valuable data.
Please keep in mind that the starting date most be equal or later than the current date of the request and the end date must be maximum 14 days ahead from the date of the request. The step of update is 3 hours.
It’s based on HTTP requests sent to the server, the response format is JSON.

Historical weather
Historical weather API provides information about the weather data in the date period for your area of interest.
It’s based on HTTP requests sent to the server, the response format is JSON.
The area of interest is set via GeoJSON notation in the body of the request, or via an area identifier received from Geometry API.
HTTP Request
POST https://api-connect.eos.com/weather/forecast-history?api_key=<your api key>
Request Parameters
| Parameter | Value | Description |
