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…

Hi HN! I'm excited to share Treasury (https://treasury.sh), a personal finance app I've been building. We just opened up our public beta and would love your feedback.

Sign up and let me know what you think.

It's at http://finkin.com. The goal is to allow a developer to sign up in seconds, and within minutes begin querying data. It runs under https and stores no access information. From http://news.ycombinator.com/item?id=1431583, I realized that all those types of sites are not tailored to developers like the other simple APIs around the web are (i.e. flickr). I made mine as simple as I thought possible.
