How it works

1. Scan or enter a barcode.
2. upc.dev checks dozens of authoritative data sources in parallel across regulatory, open-data, and marketplace categories.
3. The consensus view — name, brand, category, ingredients, country of origin, recalls — returns as JSON or rendered HTML.
4. Every signal is cached in a time-series omniscience database so changes are detectable over time.
