Hey,
this is still using the directions endpoint - since you only need the distances, I’d strongly recommend you switch to the matrix endpoint.
I am no expert in using pandas DataFrames, but after looking at this thread on the forum and the docs, something like DF.loc([['long_ced', 'lat_ced']]).values().tolist() might work to get a list of starting positions as ors matrix would expect it.
Best regards
