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 with the queried domain name and a boolean 'registered' field indicating whether the domain is currently registered/active.
Example use cases
KYB domain existence check
“I'm onboarding a new South African supplier — can you verify that their domain greencape-logistics.co.za is actually registered before I approve them?”
Competitor domain monitoring
“Is the domain mybrandname.co.za currently registered? I want to know if someone has already claimed it.”
Fraud screening for loan application
“Before we process this loan application, check whether the company domain listed on the form — rapidsolutions.co.za — is a real registered domain.”
Technical details
Endpoint
GEThttps://verza.dev/v1/domain-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call boolean check on whether a specific domain is registered, particularly in South African KYB or business verification workflows. Prefer it over general WHOIS APIs when operating in the Verza ecosystem for South African entity checks, or when you need accountless x402 micropayment access with no signup friction.
Side effects
- Missing 'domain' query parameter returns a validation error
- Invalid or malformed domain string may return an error or unexpected result
- Network timeout if the domain registry lookup is slow
- Unregistered domains return registered: false, not an error — agents must handle this as a valid result
