Google Roads API - HTTP Error 403: Forbidden

Context and problem:

I am trying to extract the speed limits of some roads using the Google Roads API. When I try to execute the basic example described on the website, I get the error HTTPError: HTTP Error 403: Forbidden. I am using the following code:

# Import libraries
import urllib.request as req

# Extract road data
key = 'my_key'
mounted_url = 'https://roads.googleapis.com/v1/speedLimits?path=38.75807927603043,-9.03741754643809|38.6896537,-9.1770515|41.1399289,-8.6094075&key=' + key 
response = req.urlopen(mounted_url)

What I have tried:

I already checked the API troubleshooting section and several similar questions:

And I already tried the recommendations given on these sites:

  • My API key is working fine. If I extract data using the Google Directions API, it works perfectly fine:
# Extract directions data
mounted_url = 'https://maps.googleapis.com/maps/api/directions/json?origin=Disneyland&destination=Universal+Studios+Hollywood&key=' + key
response = req.urlopen(mounted_url)
  • My trial is still active and the API is enabled.

Extra details:

This is the complete error:

Solution

  • After exploring the documentation for a while, I found out that this is a license problem. It seems that the speed limits feature is the only non-available feature for the Roads API trial version:
