# eu-verify LEI Validator

> eu-verify LEI Validator is a paid API for AI agents from data.greeneris.io, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).

Validates a Legal Entity Identifier (LEI) code by checking its ISO 17442 structure and ISO 7064 mod 97-10 checksum offline, returning parsed components.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability eu-verify-lei-validator-856ba30e
```

Example prompt: Can you validate this LEI code for me — HWUPKR0MPOU8FGXBT394 — and tell me if it's structurally valid and what the LOU prefix and check digits are?

## When to prefer this

Use this endpoint when you need fast, cheap offline structural validation of a LEI code without a live GLEIF registry lookup — ideal for pre-screening bulk inputs, pre-invoice checks, or KYC workflows where format correctness is the first gate. Prefer over GLEIF direct API when you want pay-per-call pricing at $0.002 USDC and no account setup, or when you only need checksum/structure validation rather than entity data enrichment.

## Known failure modes

- LEI not exactly 20 characters — returns invalid or error
- LEI with incorrect checksum — returns valid:false
- Missing 'lei' query parameter — 400 Bad Request
- Payment not provided — HTTP 402 with machine-readable USDC quote
- Non-alphanumeric characters in LEI — validation fails

## How this service works

Deterministic Legal Entity Identifier check for regulatory reporting pipelines (EMIR, MiFID II require a valid LEI per counterparty): structure regex and ISO 7064 mod 97-10 checksum over the 20-char code. Query: ?lei=HWUPKR0MPOU8FGXBT394. Returns valid, lou_prefix, entity_part and a failure reason. Filters typos before hitting the GLEIF registry (see /v1/global/lei for the live record). Pure offline, 1y cache.

## Output

Returns a JSON object with: whether the LEI is valid (boolean), the validation method (offline ISO 17442 structure + ISO 7064 mod 97-10 checksum), and the parsed components — LOU prefix (4 chars), entity part (14 chars), and check digits (2 chars). Does not perform a live GLEIF registry lookup.
