Build on Türkiye filings programmatically.

The FinancialReports API delivers SPK-supervised Turkish filings through the same single REST surface, one x-api-key header, and one shared rate-limit bucket used across all 42 covered markets. A Türkiye-only integration is a one-parameter filter (?country=TR) on the global filings endpoint — no separate KAP-tier API key, no parallel billing, no per-country infrastructure. The same endpoint returns a BIST 30 annual report, an özel durum açıklaması material-event disclosure, and a GİP admission document within the identical JSON envelope.

For live pipelines, the webhook subscription is the recommended path: subscribe once, receive a POST with full filing metadata within roughly 60 seconds of KAP publication. Turkish market hours and SPK disclosure timing mean the highest-volume periods cluster around the pre-market window and post-close announcements on Borsa İstanbul trading days. The webhook payload shape is identical across all covered markets, so a Turkish özel durum açıklaması arrives at your endpoint with the same JSON structure as a German ad-hoc or a French Informations Réglementées release. Country routing is handled server-side; consumer code stays market-agnostic.

Filing bodies are available as JSON metadata, Markdown via /api/filings/{id}/markdown/ (the processed text rendered on the public web pages), and original PDF for audit and archival use. A critical metadata field for Turkish data is the inflation-accounting flag: filings from 2023 onward for issuers applying TAS 29 carry a restatement indicator in the JSON payload, allowing downstream systems to route inflation-adjusted and nominal statements into separate processing branches without manual triage. The Markdown layer normalises KAP's variable PDF layouts — including the complex tabular structures common in Turkish banking and holding-company reports — into consistent, parseable text.

Common API integrations for Turkish data include backfilling BIST 30 / BIST 100 TFRS consolidated financials with inflation-adjustment context for EM quant research, triggering on özel durum açıklamaları for event-driven strategies (dividend announcements, Koç and Sabancı subsidiary transactions, regulatory approvals), monitoring KAP insider-transaction notifications, tracking GİP admissions and delistings, and feeding Turkish-language filings into emerging-market LLM pipelines. Trial keys are available on request; the web product is free and indexed for the public web, so coverage across the Borsa İstanbul universe is verifiable before integration.
