## 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 kyb-composite-due-diligence-ofac-gleif-sec-edgar-919eee09
```

Example prompt: Can you run a full KYB check on 'Acme Trading Ltd' — I need to know if they're on the OFAC sanctions list, whether they have a GLEIF LEI, and if they appear in SEC EDGAR, and give me an overall verdict?

## When to prefer this

Choose this endpoint when you need a one-call composite KYB verdict combining OFAC sanctions, GLEIF LEI, and SEC EDGAR data rather than querying each registry separately. Ideal for compliance automation workflows where speed and data aggregation matter more than deep per-registry pagination. Prefer over individual OFAC or GLEIF endpoints when you need all three data sources and a synthesized risk verdict in a single response.

## Known failure modes

- Company name not found in any registry — returns empty sub-objects with verdict 'clear' or 'review'
- Ambiguous name matches multiple entities — may return multiple candidates or prompt for disambiguation
- OFAC/GLEIF/SEC upstream API timeout — partial results returned with missing sub-objects
- Missing or empty 'name' query parameter — returns 400 or error response
- Name with special characters or non-Latin script may not match registry records reliably

## How this service works

KYB / KYC company screening and sanctions check in one call: OFAC SDN sanctions screening + GLEIF Legal Entity Identifier (LEI) + SEC EDGAR filings, with a composite clear/review verdict. Know Your Business due diligence on any company name. ?name=Company

## Output

Returns a JSON object with the company name, a sanctions sub-object (OFAC SDN match details), an LEI sub-object (GLEIF legal entity data), a SEC sub-object (EDGAR filings/registration data), a sources array listing which registries were queried, and a top-level verdict enum of 'clear', 'review', or 'blocked'.
