Overview

Give apps and AI agents a source-linked record of supplement labels over time. FormulaSignal’s REST API and remote MCP server support canonical product matching, current label declarations, dated formula and price history, and confirmed changes with their evidence. Create a free API key, no card or sales call.
Coverage includes U.S. pre-workouts, electrolyte and hydration products, creatine, protein powders, and some adjacent products. Historical depth varies by product, and responses surface what the evidence cannot support. Data reflects dated public sources, not lab results or claims about what is inside a physical product.
