The request https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=10,10&key=MY_API_KEY returns INVALID_REQUEST status.

Why doesn't it work?

CodePudding user response：

Although the documentation doesn't say so

Required Parameters

location
The point around which to retrieve place information. This must be specified as latitude,longitude.

Optional parameters

<snip>

radius
Defines the distance (in meters) within which to return place results. You may bias results to a specified circle by passing a location and a radius parameter. Doing so instructs the Places service to prefer showing results within that circle; results outside of the defined area may still be displayed.
...

Apparently, radius is also required in this instance, when included (along with a valid key), the service returns a response:

without radius:

https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=10,10&key=API_KEY

result:

{
   "html_attributions" : [],
   "results" : [],
   "status" : "INVALID_REQUEST"
}

with radius:

https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=10,10&radius=1500&key=API_KEY

result:
