限速不起作用，但可以捕捉到道路和其他功能

Question

当我访问此 link 时：https://roads.googleapis.com/v1/speedLimits?path=38.75807927603043,-9.03741754643809|38.6896537,-9.1770515|41.1399289,-8.6094075&key=YOUR_API_KEY for google ROADS API 它给了我以下错误：

    {
  "error": {
    "code": 403,
    "message": "Speed limits are not available for this project.",
    "status": "PERMISSION_DENIED"
  }
}

我需要提及其他 link 的工作（用于捕捉到道路，最近的道路）。只有这个抛出错误。我确保在仪表板中启用了 ROADS API，并且我检查了文档，他们在其中讨论了出现此类错误的原因（到目前为止，他们的修复程序 none 有所帮助）。

Answer 1

来自文档页面顶部的注释：

Notice: The Speed Limit service is available to all customers with an Asset Tracking license. For Google Maps Platform Premium Plan customers who transitioned to pay-as-you-go pricing, the Speed Limit feature remains active on projects with Asset Tracking capabilities (projects with a project ID in the format maps-asset-xxx).
