YAHOO! Place Finder API

Is there a way to get all of the POI (Points of Interest) and AOI (Areas of Interest) lets say for a specific state.

I would like to be able to auto-comp开发者_运维技巧lete while someone is typing if it contains any of that data, but I don't know how to get a list of all that data.

I would even be good with storing it my database if need be, because I can't see it changing very often.

No, PlaceFinder itself does not provide a way to download its places database. It's only intended for individual lookups.

You might look at the GeoPlanet data downloads which make available under CC license the entire WOEID (Where on Earth ID) geo database.
