Hi. The default transaction fee for simple_spend uses a 'high' value (this allow for transactions to be confirmed faster). I worked on your issue and will be adding it as a Pull Request. The changes I made allows for a preference parameter for the simple_spend to be called with 'low', 'medium', 'zero' or 'high' values. This will allow users to select their preferred fees. The 'zero' option though theoretically allowed may lead to transactions not being added. I consider it impractical for commercial uses but okay for testing purposes only - I may be wrong. However, if you want fine grained control you will need to generate your transaction, sign your transactions, and broadcast it as shown in the blockcypher documentation
