Building an app, a study tool, or an AI feature that needs more than raw Bible text? The IQ Bible API is a Bible knowledge API: Scripture text plus the study layer around it - original languages, lexicons, commentaries, cross-references, and audio - behind one modern API with more than 90 endpoints.^1
The text library is broad: more than 1,400 translations in more than 1,000 languages, which IQ Bible describes as public-domain and openly licensed texts, with fast passage and chapter lookup.^2 Underneath the text, Hebrew and Greek are served down to the word, with morphology and Strong's numbers, and multiple Hebrew and Greek lexicon sources are connected through a shared Strong's crosswalk.^1 Commentaries from hundreds of sources are matched to book, chapter, and verse, and a cross-reference graph links passage to passage, so one verse opens onto the rest of Scripture.^1 Audio narration, maps and illustrations, genealogies, reading plans, and devotionals round out the same data layer.^1
One endpoint is built for the newest kind of study tool: a single prompt-ready call returns Scripture, cross-references, commentary, and Strong's glosses together, designed for retrieval-augmented and LLM-powered study tools.^1 Access starts with a free API key for developers, registered through the developer portal and sent in a request header; paid tiers are usage-based, scaled by monthly request volume, with a custom enterprise tier for larger products.^1 The terms of service expressly allow personal, educational, ministry, or commercial purposes.^3
IQ Bible began as this API, which has served developers for years, and the same foundation now also powers its free, open-source Bible study app.^4 The team describes IQ Bible as "a company and ministry built for the Great Commission," and its first stated belief is simple: "Everything begins with God's Word."^4
