I would like to get the following data through Eikon's Python API.
The data (MXN forward curve 1 month starting) is available in FWDC app for the MXN currency.
Eikon Data API (Python) cannot access to specific in-10app data.
I would suggest that you contact the Refinitiv Content Helpdesk(at https://my.refinitiv.com/) to try to retrieve the information you are looking for on Eikon Excel with =TR function.
Then you can replicate that on the Eikon Data API(Python) using the same identifiers and fields..
Please note - not a content expert,but - various Curve data include Zero Coupon should be available programmatically using the RDP API or RDP Library from the Refinitiv Data Platform.
Please discuss with your Refinitiv Account representative if you wish to explore further.
