Inaccurate result searching by radius

Question

When I search using radius parameter, It returns inaccurate results. For example, radius=400, it returns distance is greater than 400. I'm wondering if the distance is not the straight line distance? Or it is a bug from foursquare api?

Answer 1

The radius parameter is "only valid for requests with intent=browse, or requests with intent=checkin and categoryId or query. Does not apply to match intent requests." See documentation here. Are you using a different 'intent'?
