Technical details
Endpoint
GEThttps://jp-local-pack-api.kasanegi123.workers.dev/api/houjin-number/lookupWhen to prefer
Use this endpoint when you need authoritative Japanese corporate registry data (official name, address, status) for a known 13-digit houjin number, especially in office automation, invoice validation, compliance, or KYC workflows targeting Japan. Prefer this over general web search when structured, machine-readable output from the official METI source is required.
Side effects
- Invalid or non-13-digit corporate number returns an error
- Corporate number not found in gBizINFO returns empty or error response
- Missing x402 payment header returns HTTP 402 with a shape preview (placeholder data, not real values)
- Network or upstream gBizINFO outage may cause failures or stale data
