@reng/pollen

Pollen grain levels for a city or lat/lon — zero OAuth, Open-Meteo Air Quality API.

Intent

Give agents and humans a small, keyless pollen pulse: geocode a place (or pass coordinates), pull hourly alder/birch/grass/mugwort/olive/ragweed grains/m³ from Open-Meteo, and return a slim summary. A lean hosted page lets a person type a city and see levels. Coverage is Europe-focused (CAMS); outside Europe pollen fields are usually null — that is expected, not a bug.

Usage

import { getPollen } from 'kody:@reng/pollen'

const berlin = await getPollen({ location: 'Berlin', hours: 24 })
// { place, coords, time, coverage, levels, peak, summary, attribution }

Or the dedicated export:

import { getPollen } from 'kody:@reng/pollen/getPollen'

Options

Coverage note

Open-Meteo documents pollen (alder_pollen, birch_pollen, grass_pollen, mugwort_pollen, olive_pollen, ragweed_pollen) as only available in Europe during pollen season (CAMS European air quality forecast, ~4 days). Calls for China or other non-covered regions typically return coverage: "unavailable" with empty levels.

Hosted app

Open the package app, type a city (try Berlin), and check levels. Posts to the same getPollen logic as the export.

Prerequisites

• No secrets / OAuth.
• Public HTTPS to geocoding-api.open-meteo.com and air-quality-api.open-meteo.com.
• Not medical advice; levels use a simple grains/m³ band for labels only.
