This API allows access to the (current) week forecast data of allergenic pollen and spores in Catalonia and the Balearic Islands, publicly available at: https://aerobiologia.cat/pia/en/forecast/catalunya, and https://aerobiologia.cat/pia/en/forecast/balears

Information includes:

  • Names of the taxons, present in the forecast.
  • Forecast table keys.
