Recipe API for Calorie Tracking Apps

Calorie counters live or die on data accuracy. Recipe API returns 32 tracked nutrients per serving on every recipe — calories, protein, carbs, fat, fiber, sugar, sodium and more — each traceable to USDA FoodData Central. Filter recipes by max_calories and min_protein, then render exact per-serving totals straight into your app.

Typical Builder Journey

1. Filter by calorie budget
Surface recipes that fit a daily or per-meal calorie target with a single query.
GET /api/v1/recipes?max_calories=500
2. Add protein and macro goals
Combine min_protein with calorie limits to balance satiety against the budget.
GET /api/v1/recipes?max_calories=500&min_protein=25
3. Render 32 per-serving nutrients
Pull full nutrition for any recipe — calories, fiber, sugar, sodium and 28 more — per serving.
GET /api/v1/recipes/{slug}
4. Trust the source data
Every ingredient links to USDA FoodData Central, so per-serving numbers are traceable, not estimated.
