What makes NutrientAPI different

Built for developers who want to own their data, their brand, and their bill.

Caching

Cache everything, forever

Cache nutrition results permanently in your own database. No TTL limits, no forced re-analysis, no data deletion on cancellation. Your data stays yours.

Branding

Your brand, not ours

Zero attribution required. No badges, no backlinks, no "powered by" line next to your nutrition facts. Ship clean, white-label experiences.

Pricing

Pay only for what you use

Start free with 25 recipes/month. Pay $0.05/recipe after that, or lock in volume with $149/mo Pro or $249/mo Max. No four-figure minimums.

Built for developers

One endpoint. Natural language in, structured nutrition data out.

NLP

Natural language parsing

Send "2 cups diced chicken breast" and we handle the rest. AI parses quantities, units, and food descriptions automatically.

2M+

USDA FoodData Central

Backed by the same database used by government nutrition programs. 2M+ foods across SR Legacy, Foundation, FNDDS, and Branded sources.

14

14 key nutrients

Calories, protein, fat, carbs, fiber, sugar, sodium, cholesterol, saturated fat, trans fat, vitamin D, calcium, iron, and potassium.

0-1

Confidence scores

Every ingredient comes with match and conversion confidence scores. Know exactly when to trust the numbers and when results need review.

v/gf

Diet and health labels
