## 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-validation-32e1fa3c -d '<json body>'
```

Example prompt: Can you verify this US Social Security Number for me — SSN 078-05-1120 — and confirm whether it's valid and tied to a real identity?

## When to prefer this

Use this endpoint when you need to programmatically verify a US Social Security Number as part of a KYC or identity onboarding workflow, especially when operating as an autonomous agent that pays per call via x402 USDC without requiring a subscription. Prefer this over generic identity APIs when you need a signed, auditable response and per-use pricing flexibility.

## Known failure modes

- Invalid or malformed SSN format returns a validation error
- SSN not found in the registry returns a not-found or empty result
- Missing required documentNumber field returns a 400 bad request
- Payment not completed or insufficient USDC returns a 402 Payment Required
- Rate limiting or quota exceeded returns a 429 error
- Network timeout results in no response
