How to Extract VM IP from API v4?

Hi Nutanix Community,I'm working on integrating with Nutanix API v4 (/api/vmm/v4.1/ahv/config/vms) for VM discovery and need guidance on the best approach for extracting VM IP addresses.I see multiple IP fields in the response and I'm not sure which one to prioritize:nicNetworkInfo.ipv4Info.learnedIpAddresses networkInfo.ipv4Info.learnedIpAddresses assignedIpAddressesand more. Is there a single field that always contains the VM's primary IP address? I'd prefer to check one reliable source instead of multiple fallbacks. What's the difference between nicNetworkInfo vs networkInfo - are they duplicates or do they serve different purposes? Thanks!

Is there a Nutanix REST API endpoint to list supported API versions like /api_version

In Nutanix Prism Central, Is there any top-level REST API that lists all supported API versions? like v2, 43, v4.0 etc.?In platforms like Pure Storage, etc., there's a REST API endpoint (e.g., GET /api/api_version) that returns a list of all supported API versions. It is useful for automation by dynamically retrieving supported REST API versions.Is there any such REST API endpoint in Nutanix?

Migration from API v3 to API v4 and backward compatibility

HiI am planning to migrate our monitoring system from API v3 to API v4. For the next 1.5 years, until API v3 is deprecated, it will be necessary to support both APIs.Based on my understanding, API v4 is supported from AOS version 6.8 and above. Our infrastructure includes a variety of PCs with different AOS versions, some of which are new (v7.0) and others that are older (v6.5) but still in use. Consequently, we need to continue utilizing API v3 for the older versions.To ensure seamless operation, I intend to implement backward compatibility to maintain both APIs until all PCs are updated, which is not expected to occur in the near future.Initially, I considered checking the AOS version or the supported API versions to determine the appropriate API version to use. Is there a general API call (not specific to any version) that can retrieve the AOS version? Please note that I do not utilize the official SDK and have developed my own implementation tailored to our specific requirements.Cu
