根据您的偏好保存内容并对其进行分类。
借助 Pollen API，您可以请求特定位置的花粉数据。花粉数据包括区域植物物种和花粉类型，以及花粉指数和健康建议。1 花粉 API 覆盖 65 个以上的国家/地区，分辨率为 1 x 1 公里（0.6 x 0.6 英里）。
该 API 提供的端点可让您查询以下信息：
Pollen API 的功能
每日花粉指数和类别预测：Pollen API 会以 1 x 1 公里（0.6 x 0.6 英里）的精细度持续计算各种花粉类型和植物指数的值。
健康建议：根据当前花粉浓度提供的健康建议。健康建议是根据花粉指数级别在植物类型级别上实施的。[^1]
植物说明详细信息：与植物及其潜在致敏效应相关的各种物种的详细信息。说明包含以下信息：类型、科、季节、特殊形状、特殊颜色、交叉反应，以及每种植物的 2 张图片。
热力图：一组可显示在 Google 地图顶部的花粉类型指数图片图块。
