DHL Extension

I cant seem to find a shipping extension that will look up shipping rates for DHL. I chatted w/ a DHL customer service rep on their site and he said they dont have a public API, but I'm not sure if he knew what I was talking about. I have a DHL Express export account number, but I don't know how to use it. How can I offer DHL as a shipping method if I cant give a customer a quote? DHL doesn't seem to offer shipping rates on their site w/o entering a bunch of info into their html form. I found a few extensions that say they offer a DHL shippping extension, but after installing them they only seem to have an enable/disable option basically. What am I missing here?

Thanks

Hi all,
does anyone know a London price for DHL shipping from Karachi, Pakistan?

I am looking for a DHL shipping module for Australia. I found the DHL International module but I cannot read dutch so I am a bit lost with the instructions.
