# 在 Duaer 里查驾车路线

在 Duaer 里：基于 OpenStreetMap 的 OSRM：两点之间的驾车距离、用时与主要道路，含备选路线。一次成功查询用 1 额度。
## 能拿到什么

Duaer 数据市场里的「驾车路线」：基于 OpenStreetMap 的 OSRM：两点之间的驾车距离、用时与主要道路，含备选路线。查到结果时用 1 额度，结果交给数字组织的下一个节点。

从节点创建器选 Duaer 数据 → 驾车路线，或打开 [数据市场](/zh/getting-started/data-market.md)。相关：[附近地点](/zh/getting-started/places-nearby.md)、[地名查询](/zh/getting-started/geocoding.md)。

## 适合做什么

- 估算两个站点之间的驾车时间。
- 为配送计划比较路线距离。

## 在画布里检索

1. 打开节点创建器，选 Duaer 数据 → Driving route。
2. 填 From 与 To，格式为 纬度,经度（如 51.5007,-0.1246）。
3. Limit 默认 10，最大 20。执行。

查到结果才扣 1 额度；没有结果、输入有误或上游失败都不扣。

## 用 API 调用

- GET https://api.duaer.com/v1/data/driving-route?from=51.5007,-0.1246&to=51.5081,-0.0759
- Authorization: Bearer <Duaer key>
