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](https://developers.google.com/maps/documentation/pollen/overview.md.txt#fn1)^ 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](https://developers.google.com/maps/documentation/pollen/overview.md.txt#fn2)^

- **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.
