Are Moz-specific ids available in response sets from V2 calls?

[StevePoul]

I'm assuming that moz assign a unique internal id to each page, subdomain and root_domain. When making v2/links requests, are these moz-specific ids available? Currently, when gathering backlinks for a client we're generating our own ids. Maintaining uniqueness is costly time-wise.

                "subdomain": "news.energysage.com",
                "root_domain": "energysage.com",

...
