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.
Example use cases
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?”
Technical details
Endpoint
GEThttps://data.greeneris.io/v1/validate/leiWhen to prefer
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.
Side effects
- 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
