}🟢check_korean_business_batch(business_numbers)
Check the registration status of up to 100 Korean businesses in a single call by their 10-digit business registration numbers (사업자등록번호). Returns one status entry per input number (order preserved) plus a summary count. Use this instead of repeated single checks when screening supplier or customer lists. Recently checked numbers may be answered from a cache up to 24 hours old (marked "cache": true). Data source: Korea National Tax Service.

}🟢find_korean_business(name, limit)
Find a Korean company by name (English or Korean) when you do not know its 10-digit business registration number — the number every other tool here needs. Returns ranked candidates with a confidence score and discriminating evidence (registration status, tax type, region), because a name can match several distinct companies: "Samsung Electronics" matches four. Sources: DART (disclosure filers, English names) and the Public Procurement Service registry (small businesses).
