Supplier re-check: send a vendor domain; get a fresh public snapshot (site up/down and redirect host, registrar, registry status, DNS, MX/SPF/DMARC, trust verdict) and whether anything changed since the last stored check. Use it on a schedule for suppliers you depend on; call vendor-what-changed for the full diff. Uncharged if a data source is down. $0.005 USDC per call on Base.
