Urantia Papers API

A developer and AI-agent friendly API for the Urantia Papers. Provides full-text search, structured content access, and audio URLs for all 14,500+ paragraphs across 197 papers.

API Endpoints

Interactive docs available at /docs (Swagger UI). OpenAPI spec at /openapi.json.

SDKs

Official TypeScript SDKs are available on npm:

npm install @urantia/api    # Typed client for all endpoints
npm install @urantia/auth   # OAuth client for accounts.urantiahub.com

See urantia.dev/sdks for documentation.

Paragraph ID Formats

The API accepts three reference formats — auto-detected from the string:

Search

curl -X POST https://api.urantia.dev/search \
  -H "Content-Type: application/json" \
  -d '{"q": "Universal Father", "limit": 10, "type": "and"}'

Search modes: and (all words, default), or (any word), phrase (exact match). Optional filters: paperId, partId.

Audio

Paragraphs include an audio field — a nested object keyed by model and voice, or null if no audio exists:

{
  "audio": {
    "tts-1-hd": {
      "nova": {
        "format": "mp3",
        "url": "https://cdn.urantia.dev/audio/eng/paragraphs/nova/tts-1-hd-nova-3:119.1.5.mp3",
        "bitrate": 160,
        "duration": 43.3,
        "fileSize": 866400
      }
    }
  }
}

Available models and voices vary per paragraph. The dedicated /audio/:paragraphId endpoint returns just the audio data for a given paragraph.

Caching

Responses include Cache-Control headers. Cloudflare's CDN caches at the edge via s-maxage:
