Submit a URL for scanningcustom_urlscan_submit_scan
Submit a URL to urlscan.io for a fresh scan. Returns a scan `uuid` and a `result` API URL to poll with get_result (results take ~10s and 404 until ready). VISIBILITY: defaults to `private` — the only truly private level. `unlisted` is hidden from public search but still visible to vetted security companies; `public` is fully public. NEVER submit URLs containing secrets, session tokens, magic-link credentials, or internal hostnames, and strip PII from URLs before scanning. This is a write action and pauses for human approval by default.
