SIATA Air Quality

Current air quality at SIATA's reference stations in the Aburrá Valley (Medellín metropolitan area): 24-hour PM2.5 and PM10, 8-hour ozone and CO, 1-hour NO2 and SO2, each as a concentration with Colombia's numeric air-quality index (ICA) and its category, plus the pollutant driving each station's index. All inputs optional: an empty body returns every station; pass latitude + longitude (with optional radius_km, default 10) for nearby stations nearest first, or municipality / station_code to narrow. Coverage is the Medellín metro area only.

Headers

Idempotency-Keystring

Example:0f8e9a42-6b7c-4d1e-9a3f-2c5d7e8f9a0b

Optional client-chosen key for this request (any string up to 255 characters, e.g. a UUID). Every Croma operation is an idempotent lookup: repeating a request with the same body returns the same result and creates nothing, so retrying after a timeout or network failure is always safe. The key is echoed back in the Idempotency-Key response header so you can correlate a retry with its first attempt. Each attempt that reaches the API counts against the rate limit.
