SIATA Citizen Air Sensors

The citizen-science PM2.5 sensor network of the Aburrá Valley (Medellín metropolitan area), about 230 low-cost sensors: PM2.5 over the last hour, the daily air-quality index (ICA) with its category, whether each sensor is reporting, and its data recovery over 24 hours and 15 days. All inputs optional: an empty body returns every sensor; pass latitude + longitude (with optional radius_km, default 10) for nearby sensors nearest first, or municipality / station_code to narrow. Indicative data; use the air-quality endpoint for the reference network.

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.
