Introducing the Search API

We’re excited to announce the launch of the Magisterium AI Search API — a powerful new way to search Catholic sources with precision, depth, and intelligence.

The Search API gives developers and organizations direct access to Magisterium AI’s curated collection of magisterial documents and scholarly works. Instead of relying on rigid keyword matching, the Search API uses advanced vector-based similarity search, meaning you can query using natural language and still receive highly relevant, context-aware results. You also have the flexiblity to choose between querying magisterial or scholarly documents (or both), as well as specify the number of results you'd like returned.

Ask a question in English, Spanish, French, or 50+ other languages, and the Search API will surface the most meaningful sources based on the intent of your query — not just the words used. This makes it ideal for building Catholic study tools, parish resources, research platforms, catechetical apps, and more.

Whether you’re building a chatbot, a digital library, or an academic research tool, the Search API helps you deliver faster, more faithful, and more accurate access to the Church’s teachings.
