LEI Structural Validator (Offline ISO 7064 Check)
x402
LEI Structural Validator (Offline ISO 7064 Check) is a paid API for AI agents from x402-datashop-production.up.railway.app, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).
Validates a 20-character Legal Entity Identifier (LEI) code offline using regex structure check and ISO 7064 mod 97-10 checksum, returning validity, LOU prefix, entity part, and failure reason.

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 indicating whether the LEI is valid (boolean), the LOU prefix (first 4 chars), the entity part (chars 5–18), and a failure reason string if the code fails the regex structure check or ISO 7064 mod 97-10 checksum. The check is performed entirely offline with no live registry call.
Example use cases
Example prompt
“Can you check whether this LEI code is structurally valid before I submit my EMIR report — HWUPKR0MPOU8FGXBT394? I want to know if the checksum passes and which part is the LOU prefix.”
Technical details
Endpoint
GEThttps://x402-datashop-production.up.railway.app/v1/validate/leiWhen to prefer
Use this endpoint when you need a fast, cheap, offline pre-validation of an LEI code before hitting the live GLEIF registry (see /v1/global/lei). Ideal for regulatory pipelines (EMIR, MiFID II) that process many counterparty LEIs and want to filter typos and malformed codes without incurring live API costs. At $0.002 USDC per call it is cost-effective for high-volume screening. Do not use this if you need live entity name, registration status, or other GLEIF record data — use the live endpoint for that.
Side effects
- LEI not exactly 20 characters — returns invalid with reason
- Non-alphanumeric characters in LEI — returns regex failure
- ISO 7064 mod 97-10 checksum mismatch — returns checksum failure with reason
- Missing required query parameter ?lei — likely 400 or error response
- Payment not made or invalid x402 auth — 402 Payment Required
