# SIATA Aburrá Valley Conditions

`POST /co/siata/v1`

## Request

- Base URL: `https://api.croma.run`
- URL: `https://api.croma.run/co/siata/v1`
- Auth: HTTP bearer

> **Deprecated.**

Deprecated since 2026-08-27; stops answering on 2026-12-01. Use `POST /co/siata-geoportal/weather/v1` instead.

Live environmental conditions for the Aburrá Valley (Medellín metropolitan area) from SIATA: per-station weather (temperature, humidity, wind, pressure), rainfall (accumulated + intensity), and air quality (24h PM2.5 + ICA index). All inputs optional: an empty body returns every station; pass `latitude` + `longitude` (with optional `radius_km`, default 10) to get only nearby stations, nearest first with `distance_km` populated. Coverage is the Medellín metro area only.

## Headers

- `Idempotency-Key` string

## Request body

- object
  - `latitude` number: Optional latitude. With `longitude`, returns only stations near that point.
  - `longitude` number: Optional longitude. With `latitude`, returns only stations near that point.
  - `radius_km` number: Radius in km around `latitude`/`longitude` to include stations. Defaults to 10.
