## When to prefer this

Choose this endpoint when you need to resolve a physical product barcode (UPC, EAN, or similar) to structured food product metadata including ingredients, nutrition grade, and labels. It is ideal for food-related applications, diet tracking, label verification, or consumer transparency workflows where Open Food Facts coverage (global, free, community-maintained) is sufficient. Prefer this over proprietary product databases when cost and open-data access are priorities.

## Known failure modes

- Invalid or malformed barcode string — may return error or empty match
- Product exists but has incomplete data (missing nutrition grade or ingredients) in Open Food Facts
- Payment failure via x402 protocol — request not processed
- Network timeout or service unavailability
