India has 17 of the world's 20 most polluted cities. The existing AQI APIs either don't cover Indian cities well, or charge $99+/month.
Antrolope is a free AQI API that works globally but is specifically built to have strong India coverage. It pulls from WAQI, OpenAQ, Open-Meteo, and OpenWeatherMap in parallel and averages the readings, giving you better accuracy than any single-source API.
There's also a /pattern endpoint that returns the optimal window to go outside today based on hourly AQI trends currently optimized for Indian cities.
Free API key at antrolope.com. Works for any city in the world.
