# SIATA Weather Station Series

`POST /co/siata-geoportal/weather-series/v1`

## Request

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

Minute-by-minute weather at one SIATA station in the Aburrá Valley (Medellín metropolitan area): temperature, humidity, wind speed and pressure over the last hour at one-minute resolution (`window: "1h"`, the default) or the last six hours at five-minute resolution (`window: "6h"`), with the source's means and temperature percentiles. `station_code` is required; codes come from the weather endpoint. Returns `found: false` for an unknown station.

## Headers

- `Idempotency-Key` string

## Request body

- object
  - `station_code` string, required: Station code, e.g. `202`. Codes come from the `weather` endpoint's `station_code`.
  - `window` '1h' | '6h': `1h` for the last hour at one-minute resolution, `6h` for the last six hours at five-minute resolution.

## Response `200`
