Overview

Scripture API is a three-phase REST API built in Go. Phase 1 delivers in-memory cached verse lookups at ~50ns. Phase 2 adds full-text and semantic search via PostgreSQL tsvector and pgvector. Phase 3 introduces cross-reference graphs and Strong's concordance word-level analysis. Deployed on GCP Cloud Run behind Cloudflare CDN with 300+ edge locations.
