{"jsonrpc":"2.0","id":1,"method":"tools/list"}hk_company_search — Search Hong Kong companies newly incorporated, registered, or renamed on the Companies Registry (香港公司註冊處, cr.gov.hk) since 30 Dec 2024 — official open data via data.gov.hk, updated weekly. Match by company name (English or Chinese, substring, case-insensitive) or an exact Business Registration (BR) number. Returns each match's BR number, English and Chinese name, company type (Hong Kong local / non-Hong Kong), incorporation-or-registration date, and any name-change date, plus the matching HKEX ticker when the name resolves to a listed stock (joined via the same Yahoo Finance lookup hk_resolve_symbol uses — only attached on a confident name match, never guessed). LIMITATION: this only covers companies newly incorporated, registered, or renamed since 2024-12-30 — it is NOT the full historical company register and does NOT return registered address or company status for companies outside that window (Hong Kong publishes no open API for those; only the Companies Registry's paid Cyber Search Centre does). Use for "is there a new HK company called X", "HK BR number for Y", "香港新註冊公司 X".hk_company — 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).hk_new_companies — Companies newly incorporated (Hong Kong local) or newly registered/re-domiciled (non-Hong Kong) on the Companies Registry since a given date — the official weekly open-data feed via data.gov.hk (新註冊/新成立公司, since 2024-12-30). Returns each company's BR number, English/Chinese name, type, and incorporation-or-registration date, most recent first. The feed has roughly a 1-week publication lag, so a `since` newer than the latest published week returns zero rows with a `data_lag_note` explaining it — that is lag, not "no new companies". Use for "new Hong Kong companies this week", "companies incorporated in HK since <date>".hk_company_name_changes — Hong Kong companies that changed their registered name, per the Companies Registry's weekly open-data feed (data.gov.hk, 公司名稱變更, since 2024-12-30). Returns each company's BR number, current English/Chinese name, and the date of the name change, most recent first. The feed has roughly a 1-week publication lag, so a `since` newer than the latest published week returns zero rows with a `data_lag_note` explaining it — that is lag, not "no name changes". Use for "Hong Kong companies that changed their name since <date>", "HK company renames this month".Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
