Drug Label Diff Tracker (DailyMed)
Pricing
Pay per usage
Watches FDA drug label (SPL) versions on your watchlist via the official NIH/NLM DailyMed API and emits section-level before/after diffs for safety sections (boxed warning, contraindications, warnings & precautions, adverse reactions) with severity heuristics and stable IDs.
All notable changes are documented here. The project follows semantic versioning; the dataset schemaVersion (currently 1.0.0) bumps on any breaking change to the output record shape.
