The Pollen API lets you request pollen data for a specific location.
Pollen data includes regional plant species and pollen types, as well as pollen
index and health recommendations.1 The Pollen API covers over 65 countries
with a resolution of 1 x 1 kilometer (0.6 x 0.6 mile).
The API provides endpoints that let you query:
Forecast: Up to 5-day pollen forecast with daily information, including
pollen index for types of plants.2
Heatmaps: Color-coded tiles of 3 pollen types.
Features of the Pollen API
Daily forecast pollen index and categories: The Pollen API
continuously calculates the value of various pollen types and plant indices
with 1 x 1 kilometer (0.6 x 0.6 mile) resolution.
Health recommendations: Recommended health insights according to the
current pollen levels. Health recommendations are implemented at the plant
type level according to the pollen index level.[^1]
Plant description details: Detailed information for the various species
that relate to the plant and its potential for allergenic effect. The
description includes the following information: type, family, season,
special shapes, special colors, cross reaction, and 2 pictures of each
plant.
Heatmaps: A collection of pollen type index image tiles that can be
displayed on top of Google Maps.
