Runs the Google URL Inspection API for one URL and stores the result in the GSC Wizard inspection history. Returns the verdict, coverage state, robots.txt state, last crawl time, the fetched/crawled-as info, the Google-selected canonical (googleCanonical), the user-declared canonical (userCanonical), and a link to the result in Search Console (inspectionResultLink). A canonical field is null when Google did not report it for this URL (common for pages it has not indexed); it is never inferred from the page. GSC enforces a daily per-property quota, so call get_inspection_quota first if you plan to inspect many URLs.
