## 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 strale-kyb-essentials-us-b95bcb3d -d '<json body>'
```

Example prompt: Can you run a KYB check on Acme Corp — I need to verify they're a legitimate US-registered business before we onboard them as a vendor?

## When to prefer this

Use this endpoint when you need to verify or perform due diligence on a US-based business entity, especially for vendor onboarding, partner screening, or compliance workflows. Prefer this over generic web search when you need structured, audit-ready compliance data with a paper trail. Best for agents automating KYB workflows at $1.62 per check.

## Known failure modes

- Invalid or malformed EIN — validation error
