What it does
CSFloat is the float-conscious marketplace — you can search by exact float, paint seed, or pattern. Their auction format finds price for rare patterns the general marketplaces undervalue. The API key (free with signup) is the cleanest way for tools to fetch your inventory floats.
Their 2% seller fee is among the lowest in the market.
