Nts Business Registration

This is a Korean National Tax Service business registration verification skill that checks whether a business number is active, dormant, or closed, and can validate registration details against official government records. It routes through a proxy server so you don't need to manage the public data portal API keys yourself. The privacy setup is notably careful: the hosted proxy strips sensitive fields from responses and doesn't cache validation requests that include owner names and addresses. If you're building Korean B2B workflows where you need to verify a supplier or partner is legit before onboarding, this hits the official NTS database. You can self-host the proxy if sending business owner PII through a third party makes your compliance team nervous.
