business.kyb-360

Full Know-Your-Business (KYB) intelligence dossier on a company, in one call. Pass name (legal/common company name); optional state narrows federal awards, and optional ticker pulls the company's SEC EDGAR identity + recent filings (SEC has no name search). Fans out to seven authoritative sources and merges them: SAM.gov registration (UEI/CAGE, active status), SAM exclusions (federal debarment/suspension), OFAC SDN sanctions screen, GLEIF LEI (legal-entity identifier + jurisdiction), USAspending federal contract awards, FARA foreign-agent registration (a disclosure status, not wrongdoing), and USPTO trademarks owned (brand/IP footprint). Returns headline riskFlags and a cleared boolean (strictly debarment + sanctions), a summary of every signal, and a found/error block per source so one slow or empty source never fails the rest. For vendor onboarding, KYB/AML, procurement due diligence, and competitive/IP research. Probabilistic name matching — confirm with a hard identifier (UEI/LEI/CIK) before acting; public records, not legal advice.

Code samples

# 1. Probe with no auth → 402 envelope with PaymentRequirements
curl -sS 'https://2s.io/api/business/kyb-360?name=xx&state=xx&ticker=example&threshold=0&limit=1'

# 2. Sign + retry with PAYMENT-SIGNATURE:
curl -sS 'https://2s.io/api/business/kyb-360?name=xx&state=xx&ticker=example&threshold=0&limit=1' \
  -H 'PAYMENT-SIGNATURE: <base64-json-payload>'

# Or use the canonical runner (handles probe → sign → retry):

#     'https://2s.io/api/business/kyb-360?name=xx&state=xx&ticker=example&threshold=0&limit=1'
