`jp_entity_check`

Pack: jp-entity-check · Connect: https://pipeworx.io/mcp (see Connect below for a single-pack URL)

No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/jp_entity_check for the schema, then POST the same URL with its arguments for the data.

Check a Japanese company or organisation against the official Japanese sources we serve in ONE call: the National Tax Agency corporate-number register, the Financial Services Agency’s EDINET filer list, its list of warned unregistered operators and its registers of licensed and registered financial operators (securities, crypto-asset, banks, insurers, funds transfer, money lenders and more), and the Ministry of Finance asset-freeze target list. Give a 13-digit corporate_number (validated, then its registered name drives the name-based sources) or a name (several register matches come back as candidates, never auto-picked). Each source returns hit / no_hit / not_checked / unavailable with what was checked, its publisher and data_as_of; unavailable (source did not answer) is never reported as no_hit. Response lists sources not covered. A hit is a lead to read in the source, not a finding about the party. Example: corporate_number=“7010401067252” or name=“Sakura Prime”.

Parameters

`corporate_number`	string	no	13-digit 法人番号 (digits only). Preferred: exact. Provide this or name.
`name`	string	no	Company or person name in Japanese or English. Provide this or corporate_number.
