Catholic IntelligenceA work of service to the Church

Developers

The register of the visible Church, as an API: over 200,000 parishes in more than 200 countries and territories, over 3,000 dioceses, every row typed, diocese-linked and geocoded. Catholic News and the day's liturgical calendar are open today, no key required. The register API opens with the register.

Quickstart: curl

Open today, no key required. Fields we do not hold come back null, never guessed.

curl "https://catholicintelligence.com/api/news?view=feed&days=3&limit=10"

Endpoints

EndpointReturns
GET /api/news?view=feed Catholic News: the ranked stories of the last days, with sources, topics and places. Parameters days, limit, lang.
GET /api/news/sources The publisher and collection-channel registry behind Catholic News. Candidate sources are identified separately from active ones.
GET /api/liturgical-today The day in the Church's year, computed rather than stored: season, week and colour from the General Roman Calendar, the celebration by name, the day's Gospel as a citation, a public-domain plate when one matches that Gospel, and the hours of the Office with the clock band each one answers to. Optional date=YYYY-MM-DD. Citations only, never the text of Scripture or the Office.

The register API

Parishes, dioceses, schools, search, and the nearest-parish tools read the register, which is in early access. One call per row: identity, contacts, schedules, coordinates, links. Sign up for early access.

Connect an AI agent (MCP)

Claude Code, one line:

claude mcp add --transport http catholic-intelligence https://catholicintelligence.com/mcp

claude.ai: Settings → Connectors → Add custom connector → URL https://catholicintelligence.com/mcp. ChatGPT: Settings → Connectors (developer mode) → Add → same URL, no authentication. Any MCP-capable client works; the transport is stateless Streamable HTTP and connects with no key. Every tool this server offers reads the register: search_parishes, get_parish, find_parishes_near, get_diocese, search_schools, get_school. They are in early access, and until launch each answers with where to sign up.

Bulk data

Complete CSV exports: the United States (over 19,000 rows), every US state, specialty cuts, national datasets for eight countries, every diocese on earth, and the world file of over 200,000 rows. Licensed by letter at licensing, with the coverage for your scope stated before anything is agreed. A sample of the columns for your scope comes back with the answer, so nothing is agreed against a description alone.

Keys, volume, and commercial use

The open endpoints are for reasonable interactive use. Keyed access with documented rate limits, bulk endpoints, webhooks, and commercial licensing are in early access: write about licensing or write to hello@catholicintelligence.com.

Honesty contract

Every count we publish is a real count from the live database, dated. Coverage varies by country and by field; where we hold nothing you receive null. Nothing is padded, projected, or generated. When citing this data, attribute "Catholic Intelligence, catholicintelligence.com" with the as-of date.
