Web-based API analysis tool

A browser tool is required that allows real-time (a) to observe the exchange rates of cryptocurrencies on various exchanges, the volume of trading, the depth of the market and other parameters, (b) to compare these parameters with each other and conduct analysis, as it is already technically decided on thematic information portals and trading platforms. The question is to collect only what is needed in one place and work on the ergonomics of data presentation. Please let me know who can make this thing. Specific data sources, wishes about graphics, interface, list of tools and other details – by letter.
