How this service works
Validate an ISO 17442 Legal Entity Identifier checksum and extract its issuing LOU prefix.
Output
Returns whether the LEI checksum is valid according to ISO 17442, along with the extracted issuing LOU prefix (the first 4 characters of the LEI code that identify the Local Operating Unit that registered the entity).
Example use cases
KYC due diligence on counterparty
“Before we onboard this financial counterparty, can you verify their LEI 254900OPPU84GM83AG37 is structurally valid and tell me which Local Operating Unit issued it?”
Bulk data cleaning for LEI fields
“I have an LEI from a client record — 7LTWFZYICNSX8D621K86 — can you check if the checksum is correct so I know whether the data entry was accurate?”
Regulatory reporting pre-flight check
“We're about to submit a trade report and need to confirm the LEI 969500CHL179N8RQAN12 passes ISO 17442 checksum validation before we file it.”

Endpoint
GEThttps://fittings.sh/v1/valid/leiWhen to prefer
Use this endpoint when you need a fast, cheap, offline-style structural validation of an LEI code — confirming checksum integrity and extracting the issuing LOU prefix — without needing to look up the live GLEIF registry. Ideal for data cleaning, pre-submission checks, and KYC pipelines where structural correctness is the first gate.
Side effects
- Invalid or malformed LEI string returns a failed validation result
- LEI not 20 characters long causes a validation error
- Missing 'lei' query parameter returns a 400 bad request
- Network timeout if the service is temporarily unavailable
