How this service works
Additives (E-numbers) declared for a food barcode, with each additive's name and function and an ultra-processing flag.
Output
Returns a JSON object containing the product name, brand, barcode, list of additives (each with E-number code, name, function, and exactness flag), total additive count, NOVA group (ultra-processing classification), a processing verdict, reasons for classification, data quality metadata, source attribution, and a disclaimer.
Example use cases
Checking snack additives before buying
“I'm about to buy these chips with barcode 028400064057 — can you tell me all the additives in them, what each E-number does, and whether it counts as ultra-processed?”
Parental food screening app
“My kid wants this cereal with barcode 038000138416. What E-number additives does it contain, and what are their functions? I want to know if it's ultra-processed.”
Diet tracking with additive awareness
“I'm tracking my additive intake — scan barcode 5000159407236 and list every food additive, its name, its function like preservative or colorant, and whether the product is in the ultra-processed NOVA group.”
Technical details
Endpoint
GEThttps://food-barcode.x402tookit.com/food-additives?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to enumerate and describe every food additive in a packaged product by barcode, including their E-number codes, functions (e.g. preservative, colorant, emulsifier), and an ultra-processing classification (NOVA group). Prefer this over the general barcode profile endpoint when additive detail is the primary concern, and over the E-number reference endpoint when you have a barcode rather than a known E-number.
Side effects
- Barcode not found in database — returns null fields or empty additives array
- Product has no ingredient data — additives array is empty and degraded flag may be true
- Invalid or malformed barcode string — query may return error or empty result
- Product exists but additive data is incomplete — partial results with notChecked list
- Network or payment failure — x402 payment required before data is returned
