Calling is probably a good idea, especially to get a letter confirming coverage (sometimes the rental car company will ask for this, more likely outside the US), but OP specifically stated what card they have- the Capital One Venture X. The terms of it's coverage are available online, and cover all countries except Israel, Jamaica, Ireland and Northern Ireland.

Pretty much no US auto insurer will cover you outside the US unless you have a very unusual policy.
