We currently use CircleCI's artifacts feature. It allows us to store our API data and website for 30 days. This retention period has been a hassle for the productive env since we need to always have these two archives built and stored on CircleCI every month, if we don't the build fails because the archives aren't present anymore.
We could instead use Github APIs and create new releases attaching our archives, then pulling those ones here in the deploy.sh script.
