Currently, the state is Assigned, however, no any ETA provided by Google. Please star it to get further updates.
I haven't managed to test it myself but this is what populartimes
offers to do in Python:
import populartimes
populartimes.get("your-api-key", ["bar"], (48.132986, 11.566126), (48.142199, 11.580047))
