I am looking for a lightweight pastebin that allows for pre-signed URLs. So that I can create a placeholder, know the URL to access it and can specify an expiration date.

I would like to use this as self-cleaning temp storage for APIs where I could register a file, handover the readonly URL to the requestor and use a edit URL to update the contents after a flow has finished.

S3 or NextCloud would allow to create pre-signed URLs for read-only and weite access but I would need to cleanup the files and the service would not be lightweight.
