Build on Taiwan filings programmatically.

The FinancialFilings API delivers FSC-supervised Taiwanese filings through the same single REST surface, one x-api-key header, and one shared rate-limit bucket used across all covered markets. A Taiwan-only integration is a one-parameter filter (?country=TW) on the global filings endpoint - the same key that accesses data for Tokyo, Seoul, and Frankfurt retrieves Taipei data at no additional cost and under no separate rate limit. For researchers who need the semiconductor supply chain in its entirety - TSMC in Taipei, Samsung Electronics in Seoul, Tokyo Electron in Tokyo, and ASML in Amsterdam - a single API key accesses all four markets through a consistent endpoint, consistent payload shape, and consistent filing-type taxonomy.

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 publication. Taiwan's tight quarterly reporting deadlines (financial statements due 30 days after quarter-end) produce a predictable high-volume delivery window in late January, late April, late July, and late October. Material-information announcements - particularly TSMC's monthly revenue releases, which are among the most closely watched data points in global technology equity research - flow as soon as they are published. The webhook payload is identical across markets; a Taiwanese material-information announcement arrives with the same JSON envelope as a Korean current report or a Dutch AFM announcement.

Filing bodies are available as JSON metadata, Markdown via /api/filings/{id}/markdown/, and original PDF. TIFRS financial data is exposed in the JSON metadata layer - because TIFRS is fully converged with IFRS, financial line-items from Taiwanese annual reports map directly to the same schema as European and Korean IFRS filings without reconciliation overhead. This cross-border schema consistency is the most practically significant feature of the platform for researchers building Asia-Pacific technology-sector financial databases: TSMC, MediaTek, and ASE Technology financials sit in the same data structure as ASML, Infineon, and STMicroelectronics. Language metadata is exposed on every filing, enabling English-only filters for the large-cap TWSE names that publish English versions.

Common API integrations for Taiwanese data include backfilling TAIEX and Taiwan 50 consolidated financials for quant research with particular depth in semiconductor capital expenditure and gross-margin tracking (TSMC's foundry economics are visible from its quarterly TIFRS statements at a granularity unavailable elsewhere), triggering on material-information announcements for supply-chain disruption signals, monitoring monthly revenue releases for the IC design cluster (MediaTek, Novatek, Realtek, Himax), and constructing cross-border semiconductor supply-chain financial databases spanning Taiwan, South Korea, Japan, and the Netherlands. Trial keys are available on request; the web product is free and publicly indexed for coverage verification before integration.
