IMHO your answer depends on your needs. Chris Butler and Dong Sun had the answers I would have picked :)

First of all, let's change our terminology. The word "POI" is too generic and broad. What you are looking for would be better referred to as a Landmark database that is already geo-referenced.

What you would do then when you are searching for all the landsmarks in that area is:

1.- geocode the input adress to find your point geometry
2.- do a spatial query to find the political boundary (city, county, state, country, etc depending on the amount of data you want back)  polygon that contains that point
3.- do a spatial query of the landmark dataset to return all the points in that area - problem solved.

The geocoding portion you can do do with any of the web services available out there.
For the political boundary datasets there are you can go with a web service model (too many solutions available out there) or just host the dataset yourself (may options here - depending on needs)
For the landmark dataset, some of the best "mainstream" data you will find will come from Navteq or TeleAtlas (commercial solutions). I am not sure if OpenStreetmaps has an API for landmarks.

Hope this helps,
