Export API for Service providers. The exported data contains coId codes that can be found here where you can also get a CSV readout to parse in your scripts.

Note that the API for import is open for KO between midnight and 7 am, and an aggregation script is run at 7:10 to create the files for downloads for XSP, so if you want as fresh data as possible, you should fetch via this API at around 8 am.
