GET /api/v1/x402/tx/:hash/screen
unprobed
Screen every address a single transaction touches. Collects the sender, recipient, token-transfer endpoints and token contracts of one transaction, then checks each against the known registry, seven sanctions lists (OFAC, UK, JP, UN, EU, CA, CH) and the ScamDB drainer database. Returns one verdict: block / review / clear. Much cheaper than a full fund-flow trace because nothing is expanded beyond…
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
