# NutriPulse

> AI-powered nutrition intelligence grounded in real PubMed research and USDA FoodData Central. Evidence-based supplement analysis, food profiles, meal analysis, personalized plans, supplement stacks, glucose pattern review, supplement-interaction checks, lab-result interpretation, longevity protocols, and prenatal nutrition — all rated by evidence quality. Pay-per-query via x402.

## What This Is

NutriPulse gives you honest, research-grounded nutrition intelligence. Every supplement claim is backed by real PubMed abstracts and rated by evidence quality (strong / moderate / emerging / limited). We tell you when the evidence is weak — that's our niche.

Data sources: PubMed E-utilities (real abstracts), USDA FoodData Central (official nutritional data), Tavily (real-time context).

All endpoints support ?lang= — Claude responds natively in any human language.
