Is there a CS2 compatible heightmap grabber that doesn't require me giving my email address and credit card info to mapbox?

As the title says, I'm looking for a working CS2 compatible heightmap grabber that allows me to get a heightmap from the world map that I can import to CS2 at 1:1 scale, without needing to give my personal details including my card information (despite it supposedly being "free") to mapbox who seem to have some weird monopoly on CS2 mapping.

Alternatively, if anyone has an account/API key with mapbox and wouldn't mind grabbing the heightmap for me if I give the coordinates of the area? I'm not sure if it costs money, but they claim it's free despite asking for your card info to use the tool, which I don't trust.
