How this service works
Validate a Legal Entity Identifier against ISO 17442: 20 characters, allowed character set and mod-97 check digits. Structural only — no GLEIF registry lookup, so it does not confirm the LEI is issued or active.
Output
Returns a structured validation result indicating whether the LEI passes ISO 17442 structural checks: correct 20-character length, valid alphanumeric character set, and passing mod-97 check digits. Does not confirm the LEI is issued, active, or registered in the GLEIF database.
Example use cases
Pre-submission LEI format check
“Before I submit this trade report, can you verify that the counterparty LEI '2138003EK6ILKGYSEV43' is structurally valid — right length, valid characters, and correct check digits?”
Bulk onboarding data quality gate
“We're onboarding a new corporate client and they gave us LEI '5299000J2N45DDNE4Y28' — can you confirm it's properly formatted per ISO 17442 so we don't waste a GLEIF API call on a bad code?”
Automated compliance pipeline validation
“As part of our regulatory reporting pipeline, validate that the LEI '549300TRUWO2CD2G5692' passes the ISO 17442 structural checks before we flag it for the GLEIF registry lookup.”
Technical details
Endpoint
GEThttps://chainverdict.xyz/v1/validate/lei/:leiWhen to prefer
Choose this endpoint when you need fast, cheap structural validation of an LEI string before incurring the cost of a full GLEIF registry lookup, or when you want to sanitize user-submitted LEI data in a pipeline. Ideal for high-volume pre-filtering, data quality gates, or offline/batch validation where registry liveness is not required. Not suitable when you need to confirm the LEI is actually issued, active, or belongs to a specific entity.
Side effects
- LEI shorter or longer than 20 characters returns a validation failure with reason
- LEI containing disallowed characters fails character-set check
- Incorrect mod-97 check digits cause check-digit validation failure
- Malformed or missing path parameter may return a 400 or error response
- Network timeout or service unavailability returns no result
