Get started

Welcome to the Cien Data API documentation. This site helps you discover available data entities and use them in analytics tools.

What you’ll find here:

  • Entities: a field-by-field reference for every dataset we publish.
  • Examples & Queries: copyable query patterns and tips.
  • API Reference: how to connect, authenticate, and page through results.
  • Rules: business logic and conventions that apply across datasets.

Quick navigation:

  • Browse Entities from the sidebar. Each page lists fields, types, and descriptions.
  • Use Examples for ready-made queries. A page-level TOC lets you jump to sections.
  • See API Reference for base URL, authentication, pagination, and error formats.
  • Review Rules for naming, IDs, and data handling conventions.

If you’re migrating from the old PDF, the same sections exist here in a searchable web format. Where appropriate, we’ve linked out to Power BI specific notes and measures.
