Technical details
Endpoint
POSThttps://x402trustlayer.xyz/api/protocol/passport/verify?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify a protocol passport specifically within the x402 trust ecosystem, particularly when the participant may be part of the certified seller network or a mandate-governed workflow. Prefer this over generic identity checks when your workflow uses x402 micropayment-gated access control and you need a trust-layer-backed allow/deny decision with an audit-friendly summary.
