Which bitcoin/cryptocurrency marketplace has the most stable and active API and support?

I am researching which marketplace I should use in my pet project that uses cryptocurrency payments.

So far I tried Binance and Coinbase but API of both seem to be either unstable (Binance) or the libraries for NodeJS are officially deprecated and there are no official replacements for them (Coinbase) which looks quite weird knowing how hot Blockchain services are these days. Documentation is a bit poor too for both.

I didn't try out Kraken yet.

So, to make a right decision, which marketplace has actively supported NodeJS libs, well-documented API and test network?
