   An API to store balances and transactions▲151

   Hey everyone! I'm Rob and I want to share what I've built - a solid ledger behind simple API: https://decimals.app The ledger is a key piece of any financial system and is easy to get the design wrong, resulting in troubles for making sure money movements are adding up. I took a lot of inspiration from good designs from Square, Uber, and others for the scalability and security aspects. And on the usability side, I applied many concepts from the Ledger CLI, making it very easy to use. I'm really happy I get to show this to you all, thank you for reading about it! Please let me know…

    I made a credit system API▲42

    I'm a solopreneur and I made it very easy to integrate a credit system into your apps and games using Creduse. I built Creduse because more and more users want pay-as-you-go models, and founders need new ways to increase user engagement or nicely limit cost-intensive features (see AI). Creduse is built by a developer for developers. I hope it will help as many startups as possible. Feedback are very much appreciated. Francesco
