Quick-scan a wallet
GET /api/public/quick-scan?address=0x...

Pay $0.01 USDC via x402. Returns in ~350ms: toxicScore (0–1), riskLevel (PASS/LOW/MIDDLE/CRITICAL), shouldFlag, and each risk trait that fired. Use shouldFlag for the off-ramp gate — any non-zero score must be blocked.

Full wallet scan
GET /api/public/scan?address=0x...

Pay $0.01 USDC. Same toxicScore and riskLevel, plus USD inflow/outflow per risk category, ENS resolution, and whether the address is a contract. Takes ~9s — use for audits and high-value decisions.

Solana wallets
GET /api/public/quick-scan/solana?address=...

Both scan modes have a /solana variant accepting USDC on Solana mainnet. Same response shape — drop-in for Solana-native agents.

Sanctions Screening
Screen persons and entities against global lists.
GET sanctions-check · $0.04
Screen a person or entity
GET /api/public/sanctions-check?name=Viktor+Bout

Pay $0.04 USDC via x402. Returns in ~50ms. Screens 1.3M+ entries from OFAC SDN, EU Financial Sanctions, UN Consolidated List, and 330+ global sources. Returns sanctioned (true/false), matchCount, and every matched entity with topics, matchedOn, and dataset provenance.

Narrow with optional params
&country=ru&birthDate=1967-01-13

Add country (ISO-2), birthDate (YYYY or YYYY-MM-DD), or address to eliminate false positives on common names. All optional — name alone is enough to start. Each extra param only narrows, never widens, results.

Solana variant
GET /api/public/sanctions-check/solana?name=...

Pay with USDC on Solana mainnet. Same response — same 1.3M+ dataset. Designed for Solana-native agents and multi-chain compliance pipelines.

Solana variant available at /api/public/sanctions-check/solana
