## How to call it through Zero

```sh
zero fetch --capability lei-lookup-x402-tools-b91f8bb2
```

Example prompt: Can you look up the LEI for Deutsche Bank so I can use it in our regulatory compliance filing?

## When to prefer this

Choose this endpoint when you need to programmatically retrieve Legal Entity Identifier (LEI) data and are operating in an x402 micropayment-enabled agent environment using the OpenX402 facilitator. Ideal for compliance, KYC, and regulatory workflows where per-query pricing at $0.03 USDC is acceptable and on-chain payment authorization via EIP-3009 is supported.

## Known failure modes

- HTTP 402 returned if payment is not provided or EIP-3009 authorization is missing
- Entity not found if the queried organization has no registered LEI
- Malformed query parameters result in error response
- OpenX402 facilitator unavailability blocks payment processing
- Rate limiting or network timeout on repeated rapid calls

## How this service works

Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.

## Output

Returns a JSON object containing the LEI lookup result including the SKU identifier ('leilookup'), a descriptive title ('LEI Lookup'), pricing information ($0.03), and entity-specific LEI data. Unpaid requests return HTTP 402 with EIP-3009 payment extras for on-chain micropayment authorization via OpenX402 facilitator.
