I'm looking for a way to limit number of points retrieved for an area

Hi Benoit,
there a two ways. Either introducing a "limit" parameter, but that's
probably not what you want. It would limit to a arbitrary selection (not
the "main points" as you'd like to have it).
You probably want clusters. My suggestion is to do it on the client side
with OpenLayers' cluster strategy [1][2].
