KYC in one call: look up a business in a US state registry (NY, CO, CT) AND screen it against the OFAC sanctions list. Give a state and a name (or exact entityId). Returns the matched registered entities (id, type, status, jurisdiction, address, registered agent) and, for each, a sanctions screen of the entity name AND its registered agent against OFAC SDN — with fuzzy-match confidence and a flagged boolean. Counterparty due-diligence, vendor onboarding, AML. Composition of /api/business/sos-search + /api/law/sanctions-check (each section reports found/error independently). Note: sanctions screening is name-based and probabilistic — review flagged matches manually.
/api/business/entity-screenPAYMENT-SIGNATURE.The entity screen API is a pay-per-call business endpoint built for AI agents and autonomous software. KYC in one call: look up a business in a US state registry (NY, CO, CT) AND screen it against the OFAC sanctions list.
There is no signup and no API key. An agent (or any HTTP client) hits the endpoint, receives an x402 "402 Payment Required" challenge, signs a sub-cent USDC payment on Base or Solana, and retries — the data comes back on the paid request. That makes it a drop-in entity screen data source for an agent tool-use loop, an MCP host, or a backend that needs business data on demand without onboarding to yet another vendor portal.
