The Weatherbit API offers robust weather, air quality, alerts and historical climate data for developers building location-aware applications. All requests require the key parameter. Base URL: https://api.weatherbit.io/v2.0/.

Key capabilities:

• Current observations by latitude/longitude and recent lightning observations.
• Forecasts: minutely (60‑minute precipitation nowcast), hourly (up to 240 hours), and daily (16 days).
• Air quality: current, 72‑hour forecasts and historical air quality data.
• Severe weather alerts from meteorological agencies.
• Sector-focused endpoints: agricultural (AgWeather) and energy forecasts (degree days, solar radiation, wind), plus historical aggregations.
• Historical datasets: hourly, sub‑hourly, daily, lightning, and climate normals.

Use cases include consumer weather apps, fleet and travel planning, agricultural decision support, energy forecasting, and environmental monitoring. See https://www.weatherbit.io/api for rate limits and full documentation.
