sn2info AND Software suggestion not working for few models

[Anand Rajasekaran]

I COLLECTED ALL DEVICES PID USING SERIAL NUMBERS USING BELOW API CALL

sn2info_url = 'https://apix.cisco.com/sn2info/v2/coverage/summary/serial_numbers/'


But For few devices, PID that were taken using  sn2info api cannot obtain the suggested version or any other information.  

software_url = 'https://apix.cisco.com/software/suggestion/v2/suggestions/software/productIds/'.

SAMPLE BELOW:PID THAT WERE COLLECTED VIA THE sn2info_url API

I'm currently working on integrating the Cisco Software Suggestion API V2 into my automation workflow, and I need to retrieve the recommended software versions for various Cisco devices. However, to do so, I first need the correct Product IDs (PIDs) for the following devices:
VG 350
VG 310
VG 420
C1-C4510R+E
WS-C4510R+E
I’ve checked the Cisco SNCheck Tool and other resources but haven’t been able to confirm the exact PIDs that should be used for API queries. Can anyone share the valid PIDs for these models or suggest a way to programmatically retrieve them?
