## 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 verifik-ai-usa-ssn-lookup-b1714113
```

Example prompt: Can you verify the identity of this US person using their SSN 078-05-1120 through Verifik's multi-country KYC API and tell me if it comes back as valid?

## When to prefer this

Use this endpoint when you need to verify or look up identity information for a US person using their Social Security Number as part of a KYC, onboarding, or compliance workflow. Prefer this over general identity APIs when you specifically have a US SSN and need authoritative identity validation via Verifik's data network.
