## 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 delx-lei-lookup-0fad99c7 -d '<json body>'
```

Example prompt: Can you look up LEI code 5493001KJTIIGC8Y1R12 and tell me the legal name of the entity and whether it's currently active?

## When to prefer this

Choose this endpoint when you need a fast, low-cost single LEI resolution against the authoritative GLEIF registry and want results with status and legal name. Ideal for agent workflows doing KYB, compliance checks, or trade document enrichment where LEI codes are already known and need to be resolved to entity details.

## Known failure modes

- Invalid or malformed LEI (not 20 characters or wrong format) — returns validation error
- LEI not found in GLEIF registry — returns not-found or empty result
- Payment failure for the $0.002 USDC x402 charge — request blocked
- GLEIF upstream unavailability — may return timeout or service error

## How this service works

Look up a 20-char Legal Entity Identifier via GLEIF for $0.002 USDC with status and legal name. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.

## Output

Returns the legal entity name and LEI registration status (e.g. ISSUED, LAPSED, MERGED, RETIRED) associated with the provided 20-character LEI code, sourced from the GLEIF registry.
