Getting CA.C fields via Eikon Data API

matthew.ang

My goal is to get vessel-related fields from Eikon Data API given a list of IMOs. Currently, I have the following code (that is working):

import eikon as ek

fields = ['TR.AssetLocationDate','TR.AssetName',
          'TR.AssetLocationLatitude','TR.AssetLocationLongitude',
          'TR.AssetLocationDraught','TR.AssetLocationDraughtPercentage']

ek.set_app_key('XXXX')
df, e = ek.get_data(imos, fields)

However, ideally I'd prefer to retrieve the CA.C counterparts of these fields (e.g. CA.C.Name, CA.C.LocationDraught)—I believe these are retrieved directly from AIS services.

Is there such a way to perform this on the Python Data API? (via ek.get_data() or otherwise)

The "CA.C.*" fields you refer to represent the metadata that was utilized in previous versions of Eikon. For backwards compatibility these fields can still be used in =RData function in Eikon Excel, but this metadata set is being phased out. "CA.C.*" fields cannot be used with Eikon Data APIs or with =TR function in Excel. "TR.*" fields in the code snippet you included replace the equivalent "CA.C.*" fields. Going forward you should utilize "TR.*" fields instead of "CA.C.*" fields.
