`hk_company`

Pack: hk-companies · Endpoint: https://gateway.pipeworx.io/hk-companies/mcp

Look up a single Hong Kong company by its exact Business Registration (BR) number in the Companies Registry’s open incorporation/name-change feed (data.gov.hk, weekly, since 2024-12-30). Returns every appearance of that BR number in the feed — its initial incorporation/registration and any later name change — with the English/Chinese name at each point, company type, and the matching HKEX ticker if it resolves to a listed stock. Returns found:false if the BR number never appears in the feed, which most often means the company pre-dates 2024-12-30 (nothing was wrong — the feed genuinely has no earlier data) or the number is not a real HK BR number. DOES NOT return registered address or company status — Hong Kong has no open API for those (香港公司註冊地址 is not published as open data; the Companies Registry’s paid Cyber Search Centre is the only source).

Parameters

Name	Type	Required	Description
`brn`	string	yes	Exact Business Registration (BR) number, e.g. “81129706”.
`since`	string	no	Search back only to this date (YYYY-MM-DD) instead of the default 12-week lookback. Use 2024-12-30 to search the entire feed (fetches more weeks, slower).
