How this service works
Pay-per-call Korean company due diligence, company ID crosswalk, sanctions screening with Korean name variants, Upbit/Bithumb risk events, HWP to Markdown, business status, business-day calendar, address normalisation, law, rates, filings and more. No account or API key: pay each call in USDC on Base via x402.
Output
Returns a JSON array of results where each entry contains the queried b_no (10-digit Korean business registration number) and a status field indicating either 'active' (the business is registered and operating) or 'invalid_number' (the number does not correspond to a valid registration).
Example use cases
Vendor onboarding KYB check
“Before we wire payment to this Korean supplier, can you verify their business registration number 1234567890 is still active and not invalid?”
Investment due diligence screening
“I'm looking at a Korean startup with registration number 2208162517 — can you confirm their business registration status is active?”
Automated compliance batch check
“We have a new Korean partner with registration number 3456789012 — please check if that business registration is valid and active before we sign the contract.”
Technical details
Endpoint
GEThttps://x402.pokt-agent.com/kr-biz/status?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, accountless, pay-per-call check of a Korean business registration number's active status — ideal for KYB (Know Your Business) workflows, vendor onboarding, or compliance screening where you only need to verify registration validity without full corporate filings. Prefer this over full due diligence endpoints when you just need a quick active/invalid status signal for a 10-digit Korean business number.
Side effects
- Missing or malformed b_no (not 10 digits) returns invalid_number or a validation error
- Payment failure via x402/USDC causes 402 Payment Required response blocking the call
- Non-existent or deregistered business numbers may return 'invalid_number' rather than a distinct 'inactive' status
- Rate limiting or upstream Korean registry downtime may cause timeouts
