## 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 gleif-lei-corporate-parent-resolver-46d311a6 -d '<json body>'
```

Example prompt: Can you look up the direct and ultimate accounting-consolidating parents for the entity with LEI 5493001KJTIIGC8Y1R12 using the GLEIF registry?

## When to prefer this

Use this endpoint when you need authoritative, GLEIF-sourced corporate parent data for a known LEI — specifically for accounting-consolidation relationships used in regulatory and financial contexts. Prefer this over general company search APIs when you already have the LEI and need structured parent-chain data with explicit exception handling. Not suitable for discovering beneficial owners, equity ownership percentages, or when you only have a company name (use the sibling LEI search endpoint first).

## Known failure modes

- Invalid LEI checksum — returns validation error before making payment
- LEI not found in GLEIF registry — entity may be deregistered or never registered
- Relationship data unavailable — entity has no reported parent (e.g. standalone entity)
- Stale data flagged — relationship record not recently updated by managing LOU
- Reporting exception present — parent intentionally not disclosed (e.g. natural person, no LEI)
- Network or service error returning 5xx

## How this service works

Resolve a legal entity's direct and ultimate accounting-consolidating parents from GLEIF's global CC0 LEI registry. Returns parent names and LEIs, relationship status, corroboration and explicit reporting exceptions. Useful for counterparty and corporate-group diligence. Not beneficial-owner identities or ownership percentages. LEI checksum validated before payment; stale results flagged.

## Output

Returns the entity's direct parent and ultimate parent (each with legal name and LEI), relationship status (active/inactive), whether the data is corroborated, staleness flags, and any explicit reporting exceptions (e.g. no LEI issued for parent, or natural person as parent).
