Thanks to @fgchiu for the tip; a server bug has been fixed, and it's now accessible via external websites. Without logging into the Binance API, you can only perform queries, but I think that should meet the needs of most users. You can either query and place your order directly on Binance, or connect to the API and I'll provide a one-click service. The downside of manual ordering is that it won't automatically buy bitcoin:native, which is essentially just a sell-put transaction, not very meaningful. However, if you really want to earn premiums and buy Bitcoin at a low price, this tool is quite useful.
