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.

Daily changes to the OFAC, EU and UN sanctions lists, plus alerts when an entity or wallet this key checked is listed. Poll this route; alerts about entities or wallets this key checked are also sent to a webhook registered for sanctions.match.new (POST /v1/webhooks). Filter by jurisdiction and severity.

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.

EU AI Act compliance readiness assessment for AI systems. Returns readiness score with gap analysis.

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.

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

Extended screening in two tiers. fresh ($0.88): politically exposed person and relative/close-associate (role.pep / role.rca) matches from OpenSanctions, with the match detail the standard entity check does not return, plus a Dutch Centraal Insolventieregister screen (NL only). enhanced ($1.71): the same plus adverse media screening against a global news index. If a source of the requested tier cannot be reached the call returns 503 and is not charged.

Historical reputation trend data. Returns the trust score timeline with the decay applied at each point and an overall trend.

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

Paid x402 endpoint for lead generation and sales prospecting workflows.

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

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. $0.11. Accepts EVM (0x...) and Solana (base58) addresses.

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).

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

Reputation scoring with linear trust decay: after its first week a score loses 2-5 points a week by risk cluster (none for a sanctions-flagged entity), plus a bonus of up to 5 points for repeat verifications.

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.
