Preflight before an agent pays an x402 seller: screens the payTo wallet against the OFAC SDN address list, reads who registered the resource domain and when (RDAP), and screens that company against the OFAC, EU and UN lists. Returns ok, caution or block with one reason per finding.

MCP tool: Screen a wallet: OFAC SDN address match, on-chain signals (contract check, native and USDC balance, transaction count, first seen on Base) and named risk rules with up to 3 advice items. On Base, also reports any ERC-8004 agent the wallet owns and its open on-chain reputation as descriptive signals, never scored. Accepts EVM (0x...) and Solana (base58) addresses.

Agent wallet check in one call: screens an EVM wallet against the OFAC SDN digital-currency address list, reads its Base USDC and ETH balance, looks up its ERC-8004 identity registration (and, given an agent id, that agent's owner and payment wallet) and lists open ERC-8004 feedback, which is not scored. Returns one verdict and each part's status; a part that could not be read says so.

ERC-8004 agent wallet balance check. Returns the on-chain USDC balance (Base mainnet) for a registered ERC-8004 agent wallet.

Sanctions screen of a company or person name against the OFAC SDN, EU and UN sanctions lists, held locally and refreshed daily. Returns each matched entry: list, entry id, matched name, programmes, countries, listing date and match score. Exact normalised or word-order-insensitive name match only; a name match is not a determination.

Know Your Business verification: company registration, sanctions screening, VAT/VIES, and domain analysis in one call.

Full entity trust check across multiple verification layers: KVK/CBE registry, OpenSanctions, country risk (CPI/FATF), domain WHOIS, IBAN validation and EU VAT/VIES. Returns trust score 0-100 with cluster and recommendation.

Quick risk score (0-100) for entity name + country. Lightweight check without full data source scan.

Lead verify for one NL or BE sales lead: is it a real, active company? Checks the KVK or KBO register and cross-checks what the lead holds: VAT with VIES, mail server and disposable domain, IBAN country and bank (not the holder), and the company name against the OFAC, EU and UN sanctions lists. Returns a verdict, a 0-100 lead score and flags, each with one action. An input not given is not checked.

Per-entity report built from one real check's signals: identity, sanctions and PEP screening, domain signals, trust score (risk.trust_score, 0-100, 100 = best), correlations with the caller's earlier reports, sources and an evidence hash. A source that did not answer is shown unavailable, never clean.

MCP tool: quick risk score for entity name + country pair.

Light company check for an agent: is the company on the NL (KVK) or BE (KBO) register and active, is its EU VAT number valid (VIES), and does its name match the OFAC, EU or UN sanctions lists? Each part says ok, not covered or unavailable. No owners, PEP or address match.

MCP tool: entity trust check for LLM agents. Runs the /v1/entity/check engine on entity_name, country, kvk_number and domain only, so up to 5 sources (no IBAN, VAT or wallet).
