I’ve had the same problem when trying to double-check the real value of USDT before making a swap. A few months ago, I was preparing a quick trade, and the rates differed so much between platforms that I started thinking something was wrong with my feed. While sorting this out, I came across a tool that updates prices almost instantly, and somewhere in the middle of comparing usdt to usd, I realized it finally gave me numbers I could trust. On this platform
paybis.com — the rate matched my actual swap results later, so now I always verify there first before hitting “confirm.”
