EDIT: This utility is defunct because the shopping API exists.
I made a utility to export buy and sell orders across multiple planets quickly. Basically you find items in the knowledge base, then click add. Once your items are added, go from planet to planet and wait for the ding before you go to the next planet. Once you’re done, run the go.bat file to concatenate your results. Delete the temp dir to reset your results.
Not described in the video: There’s also a “save planet json” checkbox. This just saves the world data json into a file when you look at a new planet portal (for those planet explorers among us).
Use at your own risk. There are security implications for your data. You accept these if you use the utility.
Let me know if you have any issues.
