How this service works
Validate a 20-character Legal Entity Identifier with the ISO 7064 mod 97-10 check and split its parts.
Output
Returns a verdict (valid/invalid), the normalised LEI string, the entity part, check digits, issuing LOU, an as-of timestamp, a human-readable summary, an array of failure reasons if invalid, a degraded-service flag, any unchecked fields, a source reference, and a disclaimer.
Example use cases
KYC onboarding entity verification
“We're onboarding a new corporate client and they've given us their LEI 549300TRUWO2CD2G5692 — can you verify it's a properly formatted, checksum-valid Legal Entity Identifier and show me its parts?”
Trade reporting compliance check
“Before we submit this trade report, check if the counterparty LEI XKZZ2JZF41MRHTR1V493 is valid according to the ISO 7064 mod 97-10 standard.”
Bulk data pipeline spot-check
“I've got an LEI from a data feed that looks off — can you run 969500T3MBS4SQAMHJ45 through the LEI validator and tell me the verdict and any reasons it might be flagged?”
Technical details
Endpoint
GEThttps://id-validators.x402tookit.com/lei-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically validate LEIs against the ISO 7064 mod 97-10 algorithm and parse their structure — particularly for KYC/AML workflows, trade reporting, and regulatory compliance pipelines where you need both a pass/fail verdict and the decomposed parts of the identifier.
Side effects
- Missing or empty 'id' query parameter returns an error
- LEI not exactly 20 characters causes validation failure
- Non-alphanumeric characters in LEI body cause rejection
- Invalid mod 97-10 checksum returns verdict 'invalid' with reasons
- Upstream LOU registry unavailable may set degraded flag and limit checks
