Response Headers

Companies

Persons

Look up individuals and their board memberships across the registry. Person lookups cost 3 credits.

Dossiers

Generate AI-powered company dossiers using an LLM with full access to registry data, change history, and enrichment. Credit cost depends on the dossier level.

Relationships

Navigate parent/subsidiary corporate structures. Each relationships or hierarchy query costs 10 credits.

News & Reports

Fetch company news from SIX and public sources (2 credits per company, 1 credit for the global feed) and parsed annual financial reports (5 credits per company).

Comparison

Compare two or more companies side-by-side in a single request. Costs 5 credits per request regardless of the number of companies compared (2–10).

Watches & Notifications

Watch companies to receive notifications when registry changes are detected. Watch management and notification retrieval do not consume credits.
