Are there any open APIs that connect to different cryptocurrencies, either with built-in capability or flexibility for plugins? Most APIs appear engineered for only one currency, usually just doge or btc. I'm wondering if there's a simpler, more adaptable solution than these coin-specific solutions, such that I could connect to multiple currencies from one code base.
Sorry if this is a dumb question. I am pretty new to cryptocurrencies, and my goal is to learn and interact with them in the most beneficial, efficient way possible.
Languages preferred include python, js, C, julia, java, R. That's just a preference, not a requirement.
