Legal entity (LEI) lookup
POST /api/lei-lookupLook up a legal entity in the official GLEIF registry. Send POST /api/lei-lookup with no required fields (2 optional) and pay $0.005 per call over x402 or MPP (there is no free tier). It returns a JSON object with found, record, parents and source.
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.
Parameters
| Name | Type | Required | Description |
|---|---|---|---|
lei | string | no | 20-character alphanumeric Legal Entity Identifier (exact record lookup). |
name | string | no | Company name to fulltext-search instead (ranked candidate list). Provide lei OR name. |
Example request
curl -i -X POST https://agent402.tools/api/lei-lookup \
-H "Content-Type: application/json" \
-d '{"lei":"HWUPKR0MPOU8FGXBT394"}'
Without payment this returns HTTP 402 Payment Required with the exact price for lei-lookup; any x402 v2 or MPP client pays it and retries.

The hosted connector at https://agent402.tools/mcp needs a payment for lei-lookup; the stdio package pays it from a wallet or from AGENT402_CREDITS_KEY. Local install: npx -y agent402-mcp.
Errors and behavior
- Every field is optional. An input the tool rejects returns an HTTP 4xx whose body carries
error,tool,expected,requiredandexample. - A paid call that ends in any status of 400 or above is not charged over x402, MPP or a prepaid credits key: settlement is cancelled when the tool fails. The exception is a Tempo push credential, a transfer the buyer sent before the call: it settles before the tool runs, so if the tool then fails the payment is recorded as a refund owed to the paying wallet.
- Wallet-only: this tool reaches the network or stored state, so it has no proof-of-work tier. A prepaid card-credits key issued earlier (
Authorization: Bearer a402_...) also pays it. - A
GETorHEADto /api/lei-lookup returns the same 402 quote, so the price can be read without a body. - An
Idempotency-Keyheader makes a retried paid call replay the first 200 instead of charging again (an answer larger than 1 MB is not replayed).
