PoetryDB vs Urantia Papers

Keyless JSON API for a curated collection of roughly 3,000 English-language poems across 129 authors, queryable by author, title, line content, or poem-count/line-count filters, with matching results returned as full structured poem objects. Built and maintained as a free open-source project with no rate limits or usage tiers documented anywhere.

Serves the complete 197-paper Urantia Book as structured JSON — by paper, section, or paragraph — with keyword search (AND/OR/phrase modes) and meaning-based semantic search, plus cross-references to Bible passages and AI-narrated audio for every paragraph. It's built for agent/RAG consumption specifically: a `/toc` endpoint enumerates the whole work up front, and `/paragraphs/:ref/context` returns surrounding paragraphs so a single retrieval call carries enough context. Reading and search endpoints are fully keyless; an optional OAuth app-registration flow exists only for personalized bookmarks and reading-progress, not for basic access.
