How this service works
Compare two packaged foods by barcode: Nutri-Score, NOVA, and per-100 g energy, sugars, saturated fat, salt, fibre and protein.
Output
Returns a structured comparison object for both products including product name, brand, quantity, Nutri-Score grade, NOVA processing group, and a per-100g breakdown of energy, sugars, saturated fat, salt, fibre, and protein. Also includes a narrative summary, a verdict on which product is nutritionally preferable, reasons supporting the verdict, data quality indicators (completeness, last modified, has ingredients), data source, timestamp, and a flag indicating if the response is degraded due to missing data.
Example use cases

Endpoint
GEThttps://food-barcode.x402tookit.com/food-compare?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a direct side-by-side comparison of two packaged foods by barcode, including structured nutritional differences, Nutri-Score grades, and NOVA processing levels in a single call. Prefer it over single-product lookup endpoints when the user's goal is to decide between two products or identify which is healthier. It is ideal for shopping-assistant agents, nutrition comparison flows, or diet-tracking applications where a comparative verdict and narrative summary are needed.
Side effects
- Barcode not found in database — product data returns null for one or both items
- Invalid or malformed barcode string — schema validation error
- Missing nutritional data for one or both products causing degraded response flag to be true
- Product data is stale or incomplete leading to low data quality completeness score
- Network timeout or upstream data source unavailability
