> CompliancePulse LEI Lookup & Validation is a paid API for AI agents from compliancepulse.theaslangroupllc.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-13).

Validates and searches Legal Entity Identifiers (LEIs) against the GLEIF ISO 17442 registry, flagging lapsed, duplicate, and retired registrations for KYB and financial reporting compliance.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability compliancepulse-lei-lookup-validation-56e177a9
```

Example prompt: Can you look up the LEI for Deutsche Bank AG in Germany and confirm whether the registration is currently active and not lapsed or retired in the GLEIF registry?

## When to prefer this

Use this endpoint when you need to verify or discover a Legal Entity Identifier for KYB workflows, MiFID II trade reporting, EMIR counterparty identification, or any regulatory context requiring ISO 17442 compliance. Prefer this over general company lookup APIs when the specific output needed is a validated LEI with active/lapsed/duplicate status from the authoritative GLEIF source. It is deterministic (no LLM hallucination risk) and covers 2.9M+ global entities.

## Known failure modes

- LEI not found in GLEIF registry — returns empty result or 404
- Invalid LEI checksum — returns validation error with checksum mismatch detail
- Ambiguous name search returning multiple candidates — agent must disambiguate by country or other fields
- GLEIF upstream unavailable — returns 503 or timeout
- Malformed LEI format — returns 400 with format error

## How this service works

Who is this company, officially? Global LEI lookup and legal-entity search against GLEIF, the ISO 17442 registry behind KYB, MiFID and EMIR reporting. Verify an LEI's checksum and registration status, or search 2.9M+ entities by name and country to find the right identifier. Flags LAPSED, DUPLICATE and RETIRED registrations that a naive first-hit lookup would wire into a KYB record. Deterministic: no LLM.

## Output

Returns the matched legal entity's LEI code, official registered name, country, registration status, and flags indicating whether the LEI is LAPSED, DUPLICATE, or RETIRED — along with checksum validity. Supports both direct LEI code validation and name/country search across 2.9M+ entities.
