Hi, thank you for dropping by.
I have not shared this with reasons,
When this is public with large query you easily do 20.000 calls to SLP API which will trigger a backoff strategy (multiple 15 minutes wait), blocking all other users of this site from attaching SPL data. Therefor i do not want random persons using this feature.
If you would like to use it i recommend to run your own version of this site. Can help you on that.
If you still needs it pop me a message on discord we can discuss.
