## 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 chainverdict-lei-validation-api-e7000c80
```

Example prompt: Can you validate the LEI code 7H6GLXDRUGQFU57RNE97 and tell me if it's active and which legal entity it belongs to?

## When to prefer this

Choose this endpoint when you need programmatic, pay-per-call LEI validation without a subscription, particularly in compliance workflows, KYB/KYC pipelines, pre-trade checks, or regulatory reporting automation. It is well-suited for low-volume or sporadic LEI lookups where a subscription-based LEI data provider would be overkill. Prefer this over manual GLEIF portal lookups when automation is needed.

## Known failure modes

- Invalid or malformed LEI (not 20 characters or wrong format) returns an error response
- LEI not found in GLEIF registry returns a not-found or invalid status
- HTTP 402 returned if payment via x402 protocol is not provided or fails
- Network timeout if the upstream LEI registry is slow to respond
- Rate limiting if too many requests are made in a short period

## How this service works

x402 v2 pay-per-call. Unpaid requests receive HTTP 402 with payment requirements.

## Output

Returns validation status and details for the given 20-character LEI code, including whether the LEI is active, lapsed, or invalid, and associated legal entity information such as registered entity name, jurisdiction, and registration authority data.
