How this service works
Packaged food by barcode (EAN-8, UPC-A, EAN-13 or GTIN-14) or by name: product name, brand, quantity, Nutri-Score, NOVA group, nutrients per 100 g (energy, fat, saturated fat, carbohydrates, sugars, fibre, protein, salt), allergens, labels, ingredients text and front image URL. Open Food Facts data (ODbL, attribution in source). A barcode not in the database is a 404, not charged. Community data: values can be missing or wrong.
Output
Returns a JSON object with count of results, the original query, data source attribution, and an array of matching products. Each product includes: name, brand, barcode, per-100g nutritional breakdown (energy kcal, fat, saturated fat, carbohydrates, sugars, fibre, protein, salt), image URL, quantity, allergen list, NOVA group, Nutri-Score letter grade, ingredients text, and labels (e.g. vegetarian, no-gluten). Also includes a checkedAt timestamp.
Example use cases
Barcode scanner nutrition check
“I just scanned the barcode 5000159484695 on a bag of crisps — can you pull up its full nutrition info, allergens, and Nutri-Score for me?”
Dietary restriction ingredient check
“I'm looking at buying Nutella (barcode 3017620422003) — does it contain any milk, nuts, or soy allergens, and what's the sugar content per 100g?”
Food product search by name
“Search for products called 'granola bar' and show me the top 3 results with their calorie counts and NOVA group classifications.”

Endpoint
GEThttps://api.sitecheck-api.workers.dev/api/food?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured food product data including nutrition facts, ingredients, and allergens for a specific packaged food item identified by barcode or name. Prefer this over general web search when you need machine-readable nutritional data conforming to Open Food Facts schema, especially for EU/international products with EAN barcodes.
Side effects
- Barcode not found in Open Food Facts database — returns empty products array
- Product name search returns no matches — returns count 0
- Invalid barcode format — may return error or empty result
- Missing required input parameters — returns validation error
- Truncated or incomplete product data when Open Food Facts entry is sparse
