Each result carries its top Urantia paragraphs (`urantiaParallelLimit`, 0 to 10, default 3). The query is embedded with `text-embedding-3-small` and matched with a pgvector HNSW index. **These are semantic parallels, not curated ones.** They show the passages closest in meaning by embedding similarity. They do not claim that two teachings are the same. ## OpenAPI ````yaml POST /scriptures/search/semantic openapi: 3.1.0 info: title: Urantia Papers API version: 1.0.0 description: >- A developer and AI-agent friendly API for the Urantia Papers.
