Legal entity (LEI) lookup

Look up a legal entity in the official GLEIF registry. Pass a 20-character LEI for the full record — legal name, jurisdiction, legal form, addresses, registration status, and the reported direct + ultimate parent entities — or pass a company name to fulltext-search the registry and get ranked candidate LEIs. Unknown LEIs return {found:false}; parents that aren't reported return null. Official registry data, keyless.

The response is HTTP 402 Payment Required with exact payment requirements. Any x402 v2 client pays automatically and retries:

Paid call (JavaScript agent)

import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client();
registerExactEvmScheme(client, { signer: privateKeyToAccount(KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agent402.tools/api/lei-lookup", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    "lei": "HWUPKR0MPOU8FGXBT394"
  }),
});
