From Source to Product Signal

Test a Product Idea in Four Steps

Start with one point and one day. The free Open-Meteo air-quality endpoint permits noncommercial use only; commercial services need separate paid access. It serves modeled CAMS air-quality context, not a direct station observation or health all-clear.

1

Check the Setup

  • Python 3.10 or newer
  • An internet connection
  • The requests Python package
2

Access the Data

  1. 1.Read Open-Meteo's noncommercial service terms and CAMS attribution guidance.
  2. 2.Request one point and one day of European AQI forecasts.
  3. 3.Preserve the model label and timestamps with displayed values.

Run the Python Example

Install the packages, then run the notebook cell.

python -m pip install requests

import requests

response = requests.get(
    "https://air-quality-api.open-meteo.com/v1/air-quality",
    params={"latitude": 52.52, "longitude": 13.41,
            "hourly": "european_aqi", "forecast_days": 1},
    timeout=30,
)
response.raise_for_status()
hourly = response.json()["hourly"]
print(list(zip(hourly["time"], hourly["european_aqi"]))[:5])

Test a Useful Signal

Inspect a Modeled AQI Day

Assess whether one forecast series supports noncommercial air-quality context.

  1. 01Keep the model source, units, and issue context with hourly values.
  2. 02Inspect missing values before displaying an AQI badge.
  3. 03Explain the noncommercial API limit and why modeled AQI is not a station reading.
