Build on Hong Kong filings programmatically.

The FinancialReports API delivers HKEX-supervised Hong Kong filings through the same single REST surface, one x-api-key header, and one shared rate-limit bucket used across all covered markets. A Hong Kong-only integration is a one-parameter filter (?country=HK) on the global filings endpoint — no separate regional API key, no per-country billing tier, no segregated infrastructure. The same endpoint that delivers DAX ad-hoc disclosures delivers Hang Seng connected-transaction circulars.

For real-time pipelines the webhook channel is the recommended path: subscribe once, receive a POST with full filing metadata within roughly 60 seconds of HKEX-News publication. The webhook payload shape is identical across all covered markets, so a Hong Kong Chapter 14A circular arrives at your endpoint with the same JSON envelope as a French AMF filing or a German BaFin ad-hoc. Country routing is handled server-side; consumer code stays market-agnostic. Hong Kong throughput spikes in the hours following the HKEX close (16:00 HKT), when the majority of results announcements and post-close circulars are published.

Filing bodies are available as JSON metadata, Markdown via /api/filings/{id}/markdown/, and original PDF. Because HKEX requires dual-language disclosure, both the English and Traditional Chinese versions of each document are indexed and accessible; language filtering is exposed as a query parameter so consumers can pull the English-only stream without a separate normalisation step. The Markdown rendering is particularly useful for connected-transaction circulars, which can be structurally complex multi-hundred-page documents; the processed text extracts the substantive content into a parseable form ready for LLM ingestion or structured information extraction.

Typical API use cases for Hong Kong data include backfilling HSI and HSCEI consolidated financials for cross-border quant research, monitoring Chapter 14A connected-transaction announcements for related-party risk surveillance, triggering on profit warnings and results releases for H-share and red-chip issuers that have no equivalent European-market disclosure obligation, and feeding bilingual English / Traditional Chinese filings into multilingual NLP pipelines. The ability to cover a Tokyo equity alongside a Hong Kong H-share within a single API call — same authentication, same payload shape, same delivery latency — is the core cross-border consistency the platform is built around. Trial keys are available on request.
