Non-SEC Chinese biotech deals and HK/STAR IPO financing — licensing agreements and IPOs with no US-listed party, read straight out of the HKEX and CNINFO exchange disclosure feeds. Keyless.

Tools

• hkex_licensing_deals(query?, since?, until?, limit?) — biotech/pharma licensing and collaboration deals disclosed by HKEX-listed companies, including deals with no US-listed party at all (e.g. a Chinese HKEX-listed biotech out-licensing to an Indian, Japanese, or European partner). Sourced from HKEXnews filings titled “License Agreement” or “Licensing Agreement”.
• hkex_ipo_filings(query?, since?, until?, limit?) — Hong Kong IPO / listing financing filings — the “GLOBAL OFFERING” prospectus and formal notice every company files with HKEX when it lists. Not biotech-specific; filter with query.
• cninfo_disclosure_search(query, board?, since?, until?, limit?) — full-text search over CNINFO, the official disclosure feed for both Chinese A-share exchanges (Shenzhen + Shanghai, STAR Market included). Covers A-share-listed companies with zero HK/US nexus — the other half of the gap.

Why this exists, and why china-pharma / pharma-deals don’t already cover it

china_licensing_deals (china-pharma) and pharma_licensing_deals (pharma-deals) are both SEC 8-K based: they see a deal only if at least one party is US-listed. A China-to-China or China-to-Japan deal between two companies with no US listing is real, disclosed, and structurally invisible to either tool. Demand log, 2026-09-13 scouting pass: 3+ real asks for exactly that class of deal, plus HK/STAR biotech IPO financing.

Two more exchanges’ own disclosure layers close the gap, both probed live 2026-09-13:

• HKEX — any Hong Kong-listed company discloses a material licensing deal or its own IPO under HKEX listing rules the same day, and HKEXnews’ public title-search JSON endpoint (titleSearchServlet.do) serves those filings without a key. This is the same endpoint nmpa_drug_approvals (china-pharma) already uses for NMPA approvals — same trick, different title term.
• CNINFO (cninfo.com.cn) — the official disclosure feed for SZSE + SSE A-shares, STAR Market included. hisAnnouncement/query is a POST endpoint, no auth, plain browser UA — verified live returning 20,703 matches for searchkey=许可 (license/licence), dated as recent as the day of the probe.

Traps

• HKEX titleSearchServlet.do ignores from/to entirely when searchType=1 and title is set — verified across three different date windows (a 9-month range, a 1-month range, and a single day in 1990) on three different title terms (“License Agreement”, “Licensing Agreement”, “Global Offering”): identical result set every time. It is a rolling most-recent-titles window, not a date-filtered query. Both HKEX tools fetch the unbounded window and apply since/until themselves, client-side — a window before the reachable range returns found: false with an explicit hint naming the actual reachable dates, never a silently-empty “nothing that period”.

• CNINFO’s board/segment filter looks like it should be guessable and isn’t. An initial probe of category=/plate=kcb for STAR Market returned HTTP 200 with the full unfiltered result set — a silent no-op, not an error. The real parameter, plate=shkcp, was found by watching the disclosure search page’s OWN network request when its 科创板 (STAR Market) checkbox is selected in the browser — the same recipe china-exchange-data used for SZSE’s report catalogs. Verified as a REAL filter, not another no-op: unfiltered searchkey=许可 returns totalAnnouncement: 20703; plate=shkcp returns 306, every one of them a 688xxx (STAR Market) code.

  Unfiltered vs. filtered, same search term, live 2026-09-13:

  plate=""      (all SZSE+SSE)  → totalAnnouncement: 20703
  plate="shkcp" (STAR Market)   → totalAnnouncement: 306   (all secCode 688xxx)

  Only star (shkcp) and chinext (szcy) are exposed as board values — both confirmed the same way. Other segments (main board, GEM) were not observed this way and are deliberately left unmapped rather than guessed; omit board to search all boards.

• CNINFO’s seDate range param genuinely filters server-side (unlike HKEX’s from/to) — confirmed by comparing a 12-day window (1 hit) against a disjoint historical month (0 hits) for the identical search term and board.

• Don’t translate a query before searching CNINFO. It is a Chinese full-text index; searching the English translation of a Chinese term returns nothing, and reads as “no disclosures” rather than “wrong language” (see reference_bilingual_entity_names — never translate-then-search).

• HKEX title search returns duplicate rows for one event. A Global Offering typically produces both a “Listing Documents” row (the prospectus PDF) and an “Announcements and Notices” row (the formal notice) for the same listing — both are returned, tagged with doc_category, rather than silently deduplicated into one.

Coverage limits, stated honestly

• hkex_licensing_deals / hkex_ipo_filings: require the Asian party to be HKEX-listed (Main Board or GEM). A private-to-private deal, or one between two A-share-only companies, is invisible here — use cninfo_disclosure_search for the A-share side.
• cninfo_disclosure_search: requires an A-share-listed party (Shenzhen or Shanghai, including STAR Market). A company listed only overseas (HK, US, or privately held) does not appear.
• A deal or listing with neither an HKEX-listed nor an A-share-listed nor an SEC-filing party (china-pharma / pharma-deals) is not visible to any tool in this catalog.
• Both HKEX tools only reach HKEXnews’ current rolling title-search window (recently, roughly the last several weeks to a couple of months, depending on how common the phrase is) — see the trap above. cninfo_disclosure_search has no such limit; its since/until genuinely reach back in time.

Auth

None. Keyless on all three tools.
