About openfoodfacts-csharp

openfoodfacts-csharp is a C package that provides access to the Open Food Facts API, a free database of over 2.9 million food products contributed by users worldwide. The library parses JSON responses from the API and transforms them into easy-to-use C objects, allowing developers to query detailed product information with minimal effort. The package supports core operations including searching and retrieving products by various parameters such as barcode, name, brand, and category. It also enables editing existing products or uploading new ones through a simple object structure, making data contributions straightforward. Most read operations do not require authentication, though setting a custom User-Agent is recommended to avoid being blocked. The package is distributed under the OdBL open data license, which encourages attribution and reciprocal contributions. Ideal use cases include building nutrition tracking apps, barcode scanning tools, dietary planning software, allergen detection systems, and any app
