SIATA

This endpoint is deprecated since 2026-08-27 and stops answering on 2026-12-01. Use its successor, POST /co/siata-geoportal/weather/v1, instead.

Queries SIATA (Sistema de Alerta Temprana de Medellín y el Valle de Aburrá) for the current readings of every monitoring station in the Aburrá Valley: weather (temperature, humidity, wind, pressure), rainfall (accumulated and intensity), and air quality (24-hour PM2.5 and ICA index). POST /co/siata/v1

Field	Type	Notes
`latitude`	number	Optional. -90 to 90. Must be sent together with `longitude`.
`longitude`	number	Optional. -180 to 180. Must be sent together with `latitude`.
`radius_km`	number	Optional. Radius in km around the point, 0-100. Default `10`.

All fields are optional. An empty body returns every station in the valley; latitude + longitude narrows the response to nearby stations, sorted nearest first with distance_km populated on each station. The response groups stations by kind: meteorology, rain and air_quality. Individual readings are null when a station hasn’t reported them. Air-quality values are 24-hour averages; updated_at marks the end of the averaging window. Without a location filter, distance_km is null on every station.

Coverage is the Medellín metropolitan area (Valle de Aburrá) only. Points outside the valley return empty arrays rather than an error.
