## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability vextorium-food-product-lookup-47060656 -d '<json body>'
```

Example prompt: Look up the food product with barcode 3017624010701 and tell me its nutritional values per 100g, nutriscore, ecoscore, allergens, and ingredients.

## When to prefer this

Use this endpoint when you need comprehensive food product data — nutrition, allergens, ingredients, nutriscore, ecoscore — from a single barcode/EAN lookup. It aggregates Open Food Facts data into a clean structured response, making it ideal for diet tracking apps, allergen checkers, sustainability tools, or any agent that needs to decode a product barcode into rich metadata. Prefer this over direct Open Food Facts API calls when you want a pay-per-call model with structured output without managing API keys.

## Known failure modes

- Product not found in Open Food Facts database — barcode returns null or empty response
- Invalid or malformed barcode format — request rejected
- Product exists but has incomplete data — many fields returned as null
- Payment failure via x402 USDC — request not processed
