## 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 verza-business-verify-south-african-kyb-api-19aa1a6b -d '<json body>'
```

Example prompt: Can you run a KYB check on a South African company with CIPC registration number 2019/123456/07, VAT number 4123456789, and email info@acmecorp.com to verify they're a legitimate business?

## When to prefer this

Use this endpoint when you need a combined KYB check on a South African business entity that ties together CIPC registration, VAT validation, and an email or non-.za domain signal in a single call. Prefer this over the free sibling endpoints (/v1/company-validate or /v1/vat-validate) when you need cross-entity corroboration (e.g. confirming a VAT number belongs to the same entity as a given email or domain). Ideal for automated supplier onboarding, marketplace fraud screening, and compliance workflows targeting South African businesses. Supports x402 pay-per-call with no account required.

## Known failure modes

- Invalid or malformed CIPC registration number returns a validation error
- VAT number format mismatch returns invalid VAT response
- Body with only .za domain provided fails because .za domains do not satisfy the body requirement
- Request with only reg or vat (no email or non-.za domain) is rejected — use the free /v1/company-validate or /v1/vat-validate endpoints instead
- Payment failure via x402 if insufficient USDC balance and no free API key
- Rate limiting or quota exhaustion on free tier

## How this service works

KYB and verification checks for South Africa: ID validation, VAT validation and NCA loan-agreement lawfulness checks against the Reg 42 interest caps. Free API key tier, or pay per call via x402 with no account.

## Output

Returns a JSON object containing the verification outcome for the South African business, including the validity status of the provided CIPC registration number, VAT number, and/or the match between the company and the supplied email or domain. Indicates whether the entity is confirmed as a legitimate registered business in South Africa.
