We are using CoinGecko.com free API to grab all exchanges market data in this plugin. Remember all data comes from thrid party APIs so we can not provide any guarantee for data accuracy, we are providing data as we are receiving from API providers. Currently CoinGecko.com is only the best free resource of crypto data API so we are using it.
If you install Cryptocurrency Exchanges List Pro plugin along with Coins Marketcap plugin then you can show list of exchanges on all coin single pages generated by Coins Marketcap plugin. Means you can compare coin price on different exchanges on a coin single page.
Yes, this plugin calls external APIs in regular intervals to show real time market data of exchanges and coins so it will consume a little more server resources than a regular WordPress plugin.
Plugin provides 2 templates for coin single page. In simple design template, you can manage page layout via shortcodes and adjustment elements positions as per your requirements. There is also an advanced template which is pre-designed in a tabbed layout by the plugin, you can add content below this but you can not edit its tabbed layout.
