Yes, there is such an API.

For example, right now I have a USB flash drive plugged into my computer.  
Its pathname is 1-4 (i.e., it is plugged into port 4 of USB controller 1).  
The information you want is available as follows:

$ cat /sys/bus/usb/devices/1-4/idProduct
1400
$ cat /sys/bus/usb/devices/1-4/idVendor 
0d7d
$ cat /sys/bus/usb/devices/1-4/serial  
07460E030679

More general access to USB devices can be programmed using libusb.
