GET https://houjin.agentic-jp.com/corporation/7010401052137
Listed in x402 List · Data: x402-list.com (CC BY 4.0)
Japanese company lookup by 13-digit corporate number (法人番号) — official trade name (Japanese and registered English), registered address, postal code, corporation kind, and lifecycle status. `status` is "active" or "closed"; a closed record carries the closure cause/date and the successor's 法人番号 after a merger. Sourced from the 国税庁 (National Tax Agency) corporate registry. The leading check digit is validated before lookup.
