Nubila API provides a comprehensive set of endpoints for accessing weather data, enabling developers to easily retrieve weather information for specific geographical locations. The API offers two primary modes of data retrieval:

• Current Weather Data - Get real-time weather conditions for a specific location

• Weather Forecast Data - Access weather forecasts for a specific location

Our API delivers detailed weather information, including key meteorological data such as temperature, humidity, wind speed, and atmospheric pressure, along with additional information like weather conditions, UV index, and more. All data is returned in a standardized JSON format for seamless integration into various applications.

Why Nubila?

What sets Nubila apart is our unique decentralized weather data collection network. Unlike traditional weather APIs that rely on sparse conventional weather stations, Nubila leverages tens of thousands of decentralized weather stations distributed worldwide. This extensive network enables us to:

• Provide Hyperlocal Data - Access precise weather information for specific locations rather than interpolated regional data

• Deliver Real-Time Updates - Get current conditions from actual on-site measurements

• Ensure Higher Accuracy - Benefit from dense sensor coverage that captures microclimate variations

• Cover More Locations - Access data from areas traditionally underserved by conventional weather stations

Our decentralized approach to weather data collection results in more granular, accurate, and timely weather information compared to traditional meteorological services.

Key Features

• Simple Authentication - API Key-based authentication system

• Standardized Format - All responses in structured JSON format

• Precise Geolocation - Weather data based on exact latitude and longitude coordinates

• Rich Weather Parameters - Comprehensive meteorological data points
