Script for executing the workflow

import json
from urllib import request, parse
import random

# load the workflow from file, assign it to variable named prompt_workflow
promptWorkflow = json.load(open('workflow_api.json'))

# give some easy-to-remember names to the nodes
loadImageNode = promptWorkflow["14"]
upscaleImageNode = promptWorkflow["71"]
wanImageToVideoNode = promptWorkflow["10"]
promptPositiveNode = promptWorkflow["13"]
KSamplerAdvancedNode = promptWorkflow["3"]

### Set workflow values from user input (parameter --source-image)
### @TODO: check that file exists before proceeding. If not, display error message

# append the input prompt to the prompt list (parameter --prompt)

# Set a random noise seed for the sampler
