Best crypto market data API for real time dashboards?

so im building a live crypto dashboard and need reliable price, volume, and market cap data. It has to stay consistent over time since we store historical snapshots. Free APIs are fine for testing but I want something that scales. Wanna know what you folks are using because a lot of results came up when I searched, eyeing a couple options like mobula.io for the free tier but havent tested it yet, wanna ask here first
