• GET /v1/business/:brno/status — Check whether a company is still operating: active, suspended or closed registration status plus tax type, looked up by business registration number. Live Korean National Tax Service (NTS) data. (0.02 USDC on Base)
• GET /v1/business/search — Search for a Korean company by name and get its business registration number. Use this when you only know what a company is called — in English or Korean — and need the 10-digit number that other lookups require. Returns ranked candidates with a confidence score and the evidence that tells similarly named companies apart: registration status, tax type and region. (0.02 USDC on Base)
• POST /v1/business/batch — Screen a supplier list against two registries at once: check up to 100 companies per call, $0.02 per number, and get registration status plus any public-procurement debarment on record. A company can be active and still barred from public contracts, so the summary counts how many are currently debarred. Live Korean National Tax Service and Public Procurement Service data.
