Technical details
Endpoint
GEThttps://saylorinnovations.com/api/allergens/product?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured allergen and may-contain declarations for a packaged food product identified by barcode, especially for allergy safety checks, dietary compliance validation, or ingredient transparency workflows. It is ideal when you already have the product's GTIN/EAN/UPC barcode and need a fast, low-cost ($0.01) lookup rather than scraping retailer pages. Prefer it over generic nutrition APIs when the specific focus is allergen and trace declarations rather than macronutrient data.
Side effects
- Product not found in Open Food Facts database (found: false) — barcode may be regional or unlisted
- Invalid barcode format — must be 8–14 digit GTIN/EAN/UPC
- Incomplete allergen data — completeness_warning field will flag missing declarations
- Open Food Facts data may be community-contributed and outdated, leading to stale or inaccurate allergen info
- Barcode belongs to a product variant not present in the database
