Tracking JPG Transactions


The problem: monitoring the purchases/sales of NFTs from a specific JPG project.

What did I do:

  1. I used Blockfrost Webhooks with the trigger condition: “policy id equal <policy ID of the project.”
  2. with Python, I located the UTXOs from the transaction hash received by endpoint URL:
  3. I located the hashes of the datas:
data_hashes = []
for i in inputs:
    if i.data_hash != None:
  1. I got the datum:
    api.script_datum(<data_hash>, return_type='json')

The problem:
a) I can’t get the value I found in “int” (I don’t know how to work well with json in python)
b) I’m not sure if this is a good solution

I appreciate any help.
