@hugoh Didn’t you read so much requests in this post to access unit price field from REST API. And you tell me, I am the only one!!! What I suggested was only a possible solution to make it faster to have this feature in REST API.
When we want to use Store Front API we should switch our App to a Sale Channel app. Our App is not a Sale Channel, and if we do that, we need to ask our 1000 Shopify shop owners to uninstall the old app and install a new sale channel app. This communication and implementation will could take for us 100 hours, but for Shopify to add new field could take some hours.
If you are really a new member in Shopify, please read the complete posts and check the possibilities a little more. If you are from Shopify, please inform your team how important this feature is.
Thank you
