# Full business-entity dossier from a state registry - master...

`GET /api/business/entity-profile`

## Request

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

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.

## Query parameters

- `state` 'CT', required
- `entityId` string
- `accountNumber` string
- `name` string
- `filingsLimit` integer
- `trial` 1

## 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.
