qgis - How to capture contour lines from OSM cycle map as vector?

In QGIS, there is a plugin to insert a OSM cycle map layer, that brings as an image from http. But I can't convert this OSM Plugin layer to a raster image. I can't even imagine how to get the contour lines that are showing by the cycle map as a vector.

Is this possible?

If is not possible through OSM, there is another open resource to get this?
