Runs every BRAND-layer rule over the business identity a 10DLC brand is registered under — legal name against the IRS record, EIN, entity type, address, the support contact the verification PIN is sent to, and the website that has to corroborate all of it. Nothing about what the brand intends to send is judged here; that is the campaign check.

Checks are free and unlimited and never consume allowance. Pass the subject as a stored-resource reference OR as an inline payload — never both for the same subject. With options.wait: true the connection is held until the verdict is ready; otherwise a fast check arrives already passed/changes_required and a slow one arrives processing for polling. options.include_website_review triggers a real crawl and is subject to a per-account daily quota.
