If the fee is not explicitly stated by the API, you can calculate it yourself very easily as it is simply the difference between the total of vIn amouts and vOut amounts for a transaction.
In the example above:
vIn = 0.03602039
VOut = 0.01 + 0.02601813 = 0.03601813
Fee = vIn - vOut = 0.03602039 - 0.03601813 = 0.00000226
great! thank you for your help!
which block explorer api would you recommend? I have found that
https://blockexplorer.com/ has been down lately... so not very reliable...
Thank you so much!
