Validating addresses for draft orders created via the API

We’re trying to validate shipping addresses for draft orders we’re creating through the API.

According to the docs, the validation is run when “You create a draft order and then add a new or existing customer to the order.” The validation does happen in the draft order UI when entering a draft manually. But we can’t figure out how to trigger a validation via the API.

We were hoping that the shippingAddress.validationResultSummary would get populated when we create a draft with a shipping address.

Anyone know if it’s possible to trigger this validation via the API before processing the order? Either when updating a draft order with the address or another way?

Also, is there a way to get the suggested address via the API when it doesn’t validate?
