nomos_asia_market_scan
Daily Market Scan (Local Artifact)
Read-only view of the most recent local daily scan artifact covering 6 regions: Japan, Singapore/China, India, Korea, Brazil/LatAm, Africa. Returns MCP-ready companies, funded entities, compliance signals. The artifact is written once per day by a separate scanner job; this tool performs no live scanning and no network requests.

nomos_crossborder_preflight
Cross-Border Regulatory Preflight
Cross-border regulatory preflight for agent data flows. Checks jurisdiction pair (EU, JP, IN, KR, SG, CN, BR, NG, ZA, MX) and data category against a local policy matrix. Returns verdict: ALLOW / ALLOW_PUBLIC_SIGNAL_ONLY / REVIEW / BLOCK (or ERROR for unsupported input), plus blocked_fields, sccs_required, risk_level, matrix_coverage and evidence_hash. Local lookup only — no network access, no legal advice.

nomos_mcp_tool_discovery
OracleNet Tool Catalog (Static)
Search a small static curated catalog of OracleNet MCP tools by keyword and category. Returns tool names, endpoints, protocol support. Local data only — does not probe, crawl or contact any network endpoint.

nomos_signed_receipt_verify
Receipt Record Lookup (Audit Log)
Look up a NOMOS operation record by its exact SHA-256 receipt hash in the local handshake audit log. Requires a full 64-hex hash, optionally 'sha256:'-prefixed; matching is exact against the stored receipt_hash/entry_hash fields. This is a record lookup, NOT cryptographic signature verification — the response always reports cryptographically_verified: false.

nomos_x402_quote
x402 Price Quote (Stateless, Unsigned)
Get a stateless, unsigned, informational x402 price quote for NOMOS services. Tier 1: $0.02 simple verdict | Tier 2: $0.05 verdict + evidence | Tier 3: $0.10 full packet. Returns payTo address, network (Base mainnet), amount in USDC atomic units, and a deterministic quote digest (not a signature). No payment is initiated and nothing is signed, persisted or reserved; expiry is informational only.
