# Look up or search the global LEI (Legal Entity Identifier)...

`GET /api/business/lei`

## Request

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

Look up or search the global LEI (Legal Entity Identifier) registry — the authoritative ISO 17442 directory of ~2.6M legal entities worldwide. Pass `lei` for an exact 20-character LEI, or `query` to search by legal/other name (ranked best-match first; the query needs at least one word of 2+ letters/digits, and the last word is prefix-matched when 3+ characters). Results page up to the first 1,000 matches (offset + limit <= 1000) — narrow with country/status rather than paging deeper. Filter name search by `country` (ISO 2-letter, HQ country) and `status` (active = currently active entities only; all = default). Each result returns the LEI, legal name, an alternate/other name, legal jurisdiction, entity category (GENERAL/FUND/BRANCH/…), ISO 20275 legal-form code, entity status (ACTIVE/INACTIVE), LEI registration status (ISSUED/LAPSED/RETIRED/…), headquarters city/region/country/postal code, the initial registration + last update + next renewal dates, and the managing LOU. Use this to canonicalize a company name to its LEI, resolve a counterparty, or enrich a vendor master. Data: GLEIF Golden Copy (CC0, public domain).

## Query parameters

- `lei` string
- `query` string
- `country` string
- `status` 'active' | 'all'
- `limit` integer
- `offset` 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).
- `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.
