Full business-entity dossier from a state registry — master record plus officers/principals, registered agent (name, phone, email, address), and filing history — the detail layer that flat registry search omits. v1 state: CT (Connecticut). Resolve by entityId (state registry record id), accountNumber, or name (partial; most recent registration wins). Returns entity status, type, registration date, mailing address, minority/woman/veteran/disability/LGBTQI ownership flags, officers, registered agent, and recent filings. KYB, vendor due-diligence, and counterparty-verification staple, sourced from the official state open-data portal.
/api/business/entity-profilePAYMENT-SIGNATURE.The entity profile API is a pay-per-call business endpoint built for AI agents and autonomous software. Full business-entity dossier from a state registry — master record plus officers/principals, registered agent (name, phone, email, address), and filing history — the detail layer that flat registry search omits.
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 profile 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.
