Runs the programme half of toll-free verification over the same profile: use case and its summary, monthly volume against what the opt-in can support, sample messages, and the opt-in evidence URL — which is the single most common cause of a toll-free rejection.

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.
