I already have a tool up using it, it's not user friendly.. it's really just a tool meant for other tools to use. http://tools.wikimedia.de/~gmaxwell/cgi-bin/deletedimage.py?hash=f85b9e4a40… hash= sha1 hash of the content of an image file. Wiki is a comma split list of databases to check. If a file with that hash has been previously deleted the tool will list it. There is a IRC bot which uses this now. It is in both #wikipedia-en-image-uploads and #wikimedia-commons-uploads2 which watches new uploads and will alert if a file which is bit-identical to a previously uploaded image is uploaded. Its output looks like: Aug 04 22:46:32 <wimb> [[User:Bladez636]] {1255} uploaded [[Image:Butters Fall.gif]] <50 × 50> <7 KB> (Tag {{PD-self}}) : This i s an Image of Butters falling from ''[[South Park]]'' this was edited using several scenes from ''[[South Park]]''.

So you want: http://tools.wikimedia.de/~gmaxwell/cgi-bin/deletedimage.py?hash=fa4d4ef502… which is what you were trying to do, and it works fine. Would base 36 input actually be useful to you? I could add a base 36 interface easily enough. I made the interface base-16 because most SHA-1 APIs output base-16 and I was told that doing conversion is hard. ;) I'm planning on adding the deletion reason and the image view URL (for sysops) next.

But do you actually have a need? I can't figure out anything to do with it on the site. I wish the site stored the MW hash for all images.. then I could come up with some really cool things to do with it. ;)
