How this service works
Does a packaged food fit a vegan, vegetarian, palm-oil-free or gluten-free diet, per its ingredient analysis and labels.
Output
Returns a verdict (e.g. 'yes', 'no', 'unknown') on whether the product meets the requested diet, along with the product name, brand, a human-readable summary, a list of reasons supporting the verdict, applicable product labels, analysis tags, data quality indicators (completeness, last modified, has ingredients), and a disclaimer about data reliability.
Example use cases
Grocery shelf scanning for vegans
“I'm at the store and just scanned barcode 737628064502 — can you tell me if this product is vegan based on its ingredients and labels?”
Gluten-free meal prep verification
“Before I buy this pasta sauce, can you check if barcode 041196898628 is gluten-free? I need to know which ingredients might be an issue.”
Palm-oil-free product screening
“I'm trying to avoid palm oil — can you look up barcode 8712566312207 and tell me if it's palm-oil-free, and why or why not?”

Endpoint
GEThttps://food-barcode.x402tookit.com/food-diet-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, structured diet-compatibility verdict for a specific packaged food identified by its UPC or EAN barcode. It is purpose-built for the four diets (vegan, vegetarian, palm-oil-free, gluten-free) and returns interpretable reasons, not just a boolean. Prefer it over a general product lookup endpoint when the user's goal is specifically dietary compliance rather than nutritional analysis or allergen checking.
Side effects
- Barcode not found in database — verdict and name may be null
- Unknown or ambiguous ingredients — degraded flag set to true with reduced confidence
- Diet type not supported — request rejected or empty response
- Incomplete ingredient data — notChecked array lists unverified ingredients
- Stale product data — dataQuality.lastModified may be outdated
