I'm trying to get keywords from any webpage I provide as a param. Unfortunately meta-tag keyword data is no longer used and DIY text-parsing usually takes to long per request. So I'm looking for one of the following two solutions:

Solution 1: a URL to Keyword API Does anyone know of an API/service that allows you to send over the URL of a webpage and get keywords or refined categories back?

or Solution 2: a quick text-parsing method Or is there any a quick (1s/request) easy text-parsing method on either the server-side (php) or client-side javascript that could return me a half-way decent set of keywords about any webpage I give it?
