Api Endpoint

OnChainDiligence

Verify a US public company against SEC EDGAR. Look up an SEC-registered issuer by ticker, CIK, or name and get its legal entity name, industry (SIC), state of incorporation, tickers/exchanges, and latest filing. For ambiguous names, returns candidates without selecting a company. For KYB, counterparty due diligence, and issuer verification.
