Open Food Facts loves science (and scientists)

Open Food Facts sustainable API Proxy

• No owner yet.
• Open Food Facts API usage is free and will remain free for all users. Though, it is made for reasonable usages: 1 API call = 1 real scan by a user. Our resources are not sized for dozens of requests at a time. For example, while building dashboards with Google Spreadsheet is feasible via Open Food Facts API, we tend to block this kind of request as it consumes too many resources. The goal of OFF API Proxy is to allow dozens of requests at a time, the proxy queuing requests passing them to the API at a reasonable rate (2 requests/s). The proxy is also using caches, allowing a more sustainable usage of the API.
• Needs: If you do have Nginx skills, your contribution would be appreciated.
