Unfortunately no, this was entirely custom closed source code and customized for one specific use. But you can try making your own map server, when you have data in postgis and search a little, geodecoding is rather easy. Just find geometry with specific tags near your point, then select nearest street number, street name, administrative zone names. I've tested first on one country (low space requirements), importing whole europe can take several days even for multicore servers with ssd.
