About DietlyAPI

DietlyAPI is a food and nutrition data API providing access to a database of over 4.2 million foods, combining an Open Food Facts catalog with Dietly community entries and labeled AI-estimated entries. It offers endpoints for fuzzy full-text search, EAN-13/UPC-A barcode lookup, single-food retrieval by ID, popular foods, and food categories, returning calories, macros, and micronutrients with source-labeled, confidence-ranked results (complete label data ranked above sparse entries, which rank above AI estimates). The origin is hosted in Nuremberg, Germany, with Cloudflare's edge network terminating TLS for global requests, and a public status page reports uptime and probe latency history.

The API is aimed at developers building nutrition, fitness, or food-tracking apps who need calorie and macro data without importing and normalizing raw datasets themselves. Read endpoints (search, barcode, food lookup) work without an account at 30 requests/minute per IP with a configured fairness delay; registering a free API key requires only a username, password, and verified email, and removes the fairness delay in favor of plan-based limits. Authentication uses a single Bearer key.

Pricing includes a free Starter tier (30 req/min per IP, non-commercial use), a Pro tier at €27/month (500 req/min per account, commercial use license, no overage charges), a Scale tier at €92/month with a 14-day free trial (3,000 req/min per account), and a custom Enterprise tier starting from $0.0002/call with volume pricing, bulk dataset exports, custom data licensing, and invoiced billing. All plans include access to the full food database; higher tiers add throughput, commercial use rights, and support level.
