user77850: I am trying to build an app that will pull in all my wallet balances. I can easily do this with exchange apis, but how do I get balances that are stored in wallet?
Do I need to set up bitcoind, litecoind, neo equivalent, and all of the rest? That sounds like a lot of work and A LOT of server space / resources?
I'm surprised I haven't been able to find a single unified api provider, where I can just send a BTC address, or a LTC address or a NEO address and it returns me a balance. Does such a thing not exist?
Thanks :)

You don't have to; you can use different APIs for different coins. But not all coins will have a service that offers that, so for those you will need to run your own node software.

You've answered this yourself:

It's simply too expensive for someone to do that.
