Overview

BreezoMeter Pollen API (now part of Google Maps Platform) provides daily pollen forecast data including pollen type, index values, and risk levels for a specific geographic location. An API key from Google Maps Platform is required to authenticate requests. It is valuable for building health apps, outdoor activity planners, or allergy alert systems.

Beginner Tip

Enable the Pollen API in your Google Cloud Console project and make sure billing is set up — the API has a free tier but requires a billing account. Use latitude and longitude coordinates (not city names) when querying pollen data.

Available Data

The kind of data this API exposes, based on its documentation. We could not call the endpoint to confirm the exact field names.

Example Response

Illustrative shape only — we were not able to call this endpoint (it requires credentials or exposes no public sample URL), so the fields below show the kind of data this API returns rather than a recorded response.

Field Reference

dailyInfo Array of daily pollen forecast objects, one per requested day.
dailyInfo[].date Date of the forecast with year, month, and day fields.
dailyInfo[].pollenTypeInfo List of pollen types (e.g., GRASS, TREE, WEED) with index and risk level.
pollenTypeInfo[].indexInfo.value Numeric pollen index value indicating concentration level.
pollenTypeInfo[].indexInfo.category Risk category such as None, Very Low, Low, Medium, High, or Very High.
pollenTypeInfo[].inSeason Whether this pollen type is currently in season for the location.

Implementation Example

Calls a real endpoint of this API. Replace any placeholder credentials with your own key.

Request
const url = "https://docs.breezometer.com/api-documentation/pollen-api/v2/";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
  headers: {
  "X-API-Key": "YOUR_API_KEY"
  }
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

Common Errors & Troubleshooting

Generated guidance based on this API's documentation, not observed by us. Treat it as a starting point and check against the provider's own error reference.

403 Forbidden - API not enabled The Pollen API has not been enabled in your Google Cloud project.
Go to the Google Cloud Console, navigate to APIs & Services, search for Pollen API, and enable it for your project.
400 Bad Request - invalid location Location must be provided as latitude/longitude, not a city name string.
Use numeric lat/lng values like location.latitude=37.7749&location.longitude=-122.4194.
403 Billing not enabled Google Maps Platform requires an active billing account even for free-tier usage.
Set up a billing account in Google Cloud Console and link it to your project.

Metadata Score Breakdown

Estimated from metadata — endpoint not independently tested

This score is estimated from observable metadata — HTTPS support, authentication model, declared CORS, and documentation reachability — because the API requires authentication or exposes no publicly testable endpoint. The five-signal breakdown is only shown for live-tested APIs.
