Is a SIP simular to an API?

I know what a SIP is; what is an API?
Though the SIPs I am familiar with are slightly different than those described above. The SIPs that I have seen are just styrofoam type insulation sandwiched between OSB. They come with chase for wiring anyhere you want them placed. Typically 12" to 18" off floor for outlets and 48" for switches as well as specified height for countertop receptacles and out side lighting. There are also verticle chases where ever specified.

I might add that I think they are a pain in the A** to wire, but they provide excellent insulation for a home.
