I'm working on a personal finance tracking app and I need to access balances and possibly transactions for American Express users. I'm currently using TrueLayer for most of my bank integrations, but they don't include Amex. I'm hoping to find a platform that supports American Express and allows me to use it for a personal project without having to pay. Does anyone know of such a solution?

Finding a free option for personal use is tough, especially in the US where banking is heavily regulated. I’m also working on a personal finance app, focusing on cash flow rather than net worth. I’ve had decent luck just using CSV files for transactions—though it's a manual process, it keeps my data private.
It’s important to check if American Express offers open banking access at all. They do have their own platform, but you’ll need to go through a certification process like most banks. That’s one reason why services like Plaid exist—they handle the certification for businesses, but unfortunately not for hobby projects.
