# Full Know-Your-Business (KYB) intelligence dossier on a...

`GET /api/business/kyb-360`

## Request

- Base URL: `https://2s.io`
- URL: `https://2s.io/api/business/kyb-360`
- Auth: API key in header `PAYMENT-SIGNATURE`

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 six 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, and FARA foreign-agent registration (a disclosure status, not wrongdoing). 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, and procurement due diligence. Probabilistic name matching — confirm with a hard identifier (UEI/LEI/CIK) before acting; public records, not legal advice.

## Query parameters

- `name` string, required

## Other responses

- `200` (unresolved $ref)
- `400`: Invalid request — not charged. error.code: BAD_REQUEST or INVALID_PARAM (parameter validation; error.details.issues lists each problem), MALFORMED_JSON, or a request-specific code. Other client errors: 405 METHOD_NOT_ALLOWED (wrong verb; see the Allow header), 413 PAYLOAD_TOO_LARGE.
- `402`: Payment required. Body is the x402 PaymentRequirements envelope with a multi-network accepts array; the per-call price is in accepts[].amount (and on the operation as x-2s-price). Sign for whichever rail you hold USDC on (EIP-3009 for Base, partial SPL transfer for Solana) and retry with the PAYMENT-SIGNATURE header (X-PAYMENT also accepted for v1 clients). Also PAYMENT_SETTLE_FAILED (error envelope) when a verified payment failed to settle: error.details.chargeStatus is "not_charged" (retry with a fresh payment) or "unknown" (the authorization may still settle before its deadline — check it before retrying).
- `404`: Not found — NOT_FOUND (or NO_SOURCES / NO_OPINIONS): the requested entity does not exist. Not charged.
- `429`: Too many requests — RATE_LIMITED: our per-IP / per-payer limiter. Not charged; retry after Retry-After.
- `5XX`: Server-side failure. 500 INTERNAL: unexpected error; quote error.errorId (also the X-2s-Error-Id header). 502 UPSTREAM_UNAVAILABLE (or another UPSTREAM_* code): the data provider failed — composite endpoints refuse unbilled when every source fails. 503 SERVICE_PAUSED: endpoint paused by the operator kill switch, retry after Retry-After; 503 SPEND_CAP: daily upstream budget exhausted. 504 UPSTREAM_TIMEOUT. Not charged.
