Build on Luxembourg filings programmatically.

The FinancialReports API delivers CSSF-supervised Luxembourg 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 Luxembourg-only integration is a one-parameter filter (?country=LU) on the global filings endpoint — no separate Luxembourg API key, no additional billing, and no per-country segregation. Bourse de Luxembourg annual reports, CSSF ad-hoc announcements, and insider-transaction notifications are all served from the same endpoint.

Filing volume for Luxembourg is lower in absolute terms than for larger European equity markets, reflecting the compact operating-company universe. For that reason, polling the filings endpoint on a scheduled basis is a reasonable alternative to the webhook channel for integrations that don't require sub-minute latency. Where real-time delivery is needed — for example, triggering on earnings announcements from ArcelorMittal or Eurofins — the webhook subscription delivers the same sub-60-second latency as for all other covered markets, with an identical JSON payload shape.

Filing bodies are available as JSON metadata, Markdown via /api/filings/{id}/markdown/, and original PDF or iXBRL. The multilingual filing environment — French, English, and German versions may exist for the same document — is reflected in separate filing records per language version, with language metadata in the JSON payload allowing consumers to select the preferred language without parsing the document itself. iXBRL is preserved for ESEF-mandated annual reports, retaining machine-readable financial line-items.

Common API integrations for Luxembourg data include pulling consolidated IFRS annual reports for holding groups (ArcelorMittal, Eurofins, SES) where Luxembourg is the primary regulatory domicile, combining the Luxembourg feed with the Amsterdam or Italian feed for dual-listed issuers, monitoring CSSF insider-transaction and threshold-crossing notifications, and constructing multi-country filing pipelines for pan-European holding structures where subsidiaries report across several covered markets. Trial keys are available on request; the web product is free and indexed for the public web.
