# Cross-border transfer preflight: one call returns ALLOW / ALLOW_PUBLIC_SIGNAL_ONLY / REVIEW / BLOCK with adequacy status, risk level and SCC requirement.

`POST /v2/nomos/preflight`

AgentNOMOS Cross-Border Regulatory Compliance Preflight. Checks a planned cross-border data transfer between EU, India, Japan, Korea, Singapore and China against GDPR, DPDP, PIPL, FSA and MAS. Returns one verdict for the request (ALLOW, ALLOW_PUBLIC_SIGNAL_ONLY, REVIEW or BLOCK) inside `preflight_summary`, together with adequacy_status, risk_level, sccs_required, requires_human_review, blocked_fields and evidence_hash, plus scanned target candidates and a SHA-256 receipt_hash. Target-specific fields are withheld automatically when the verdict does not permit them. Classification only, not legal advice.
