How this service works
Look up a packaged product by GTIN/barcode via Open Food Facts (global). Returns the normalized nutrition profile plus allergens, diet flags, Nutri-Score and NOVA.
Output
Returns a normalized nutrition profile (macronutrients, energy, etc.), allergen list, dietary flags (vegan, vegetarian, gluten-free, etc.), Nutri-Score letter grade, and NOVA food processing classification for the matched packaged product.
Example use cases
Check allergens for customer safety
“I just grabbed a snack from the shelf—barcode is 737628064502. Can you tell me what allergens are in it? My customer has a peanut allergy and I want to make sure it's safe.”
Verify vegan product claims
“This product says it's vegan on the label, but I want to double-check. Can you scan barcode 5449000051128 and confirm whether it's actually vegan or if there are any hidden animal-derived ingredients?”
Compare Nutri-Score across variants
“I'm trying to pick the healthier cereal for my kids. Can you look up the Nutri-Score and nutrition facts for barcode 8711000702123 and tell me if it's a good choice compared to typical breakfast cereals?”
Technical details
Endpoint
GEThttps://payai.agentstools.dev/nutrition/barcodeWhen to prefer
Use this endpoint when you have a physical product barcode (EAN/UPC/GTIN) and need structured nutrition data, allergen information, or dietary classification (Nutri-Score, NOVA) for a globally sold packaged food. Prefer this over manual ingredient lookup when a barcode is available and you need standardized, machine-readable output.
Side effects
- Barcode not found in Open Food Facts database — returns empty or 404-like response
- Invalid barcode format (fewer than 8 or more than 14 digits) — returns validation error
- Product exists but has incomplete data — partial nutrition profile returned
- Upstream Open Food Facts API unavailable — returns service error
- Barcode resolves to non-food product with no nutrition data
