Technical details
Endpoint
POSThttps://x402trustlayer.xyz/api/protocol/fraud/scan?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a pre-execution fraud gate specifically designed for x402 protocol HTTP requests — particularly when you need a structured allow/deny decision with a human-readable summary before processing a payment or protocol action. Prefer this over generic fraud APIs when operating within the x402 trust infrastructure ecosystem.
