How this service works
Returns the nutritional values per hundred grams, the Nutri-Score and NOVA processing group, the environmental score where available, and the packaging composition, each with the data that produced it. A Nutri-Score without its inputs is a grade without a calculation: fibre and the fruit and vegetable share move the result substantially, and when they are absent the score is computed from what remains without that being visible in the grade itself.
Output
A structured response containing: nutritional values per 100g (energy, fat, saturated fat, carbohydrates, sugars, fibre, protein, salt), the Nutri-Score letter grade alongside all the input values (including fibre and fruit/vegetable fraction) that produced it, the NOVA processing group classification, an environmental score where data is available, and packaging material composition — all with the source data that generated each score for full transparency.
Example use cases
Transparent Nutri-Score audit for a recipe
“I've got a product with 6g protein, 12g fat, 3g saturated fat, 18g sugar, 2g fibre, and 40% fruit/vegetable share per 100g — can you compute the Nutri-Score and show me exactly which inputs pushed the grade up or down?”
NOVA group check for processed food labeling
“I need to classify this ready-meal product by its level of processing — run it through NOVA and tell me which group it falls into along with the ingredients that determined that.”
Eco-score and packaging audit for sustainability report
“For our sustainability dashboard, can you get the environmental score and full packaging composition breakdown for this product so I can see what materials are used and how they affect the eco rating?”
Technical details
Endpoint
POSThttps://handel.halowerk.com/v1/nutrition-ecoWhen to prefer
Choose this endpoint when you need not just the Nutri-Score letter grade but the full set of inputs that produced it — especially fibre and fruit/vegetable share, which substantially shift the result and are often missing from summary-only sources. Prefer it over barcode-lookup endpoints when you already have product data and need transparent, auditable computation. It is also the right choice when you need NOVA group, environmental score, and packaging composition in a single call rather than assembling them from separate APIs.
Side effects
- Missing fibre or fruit/vegetable share causes Nutri-Score to be computed from partial inputs without the grade reflecting that gap
- Environmental score unavailable if product lacks sufficient sourcing or lifecycle data
- Invalid or incomplete nutrient data returns validation error or partial results
- Packaging composition absent if product data does not include material declarations
- Rate limiting or payment failure returns 402 or 429 error
