CS2 Skin Price & Float API
The CSAlpha Developer API delivers programmatic CS2 skin pricing and float data built from real, buyable marketplace listings across CSFloat, DMarket, and Skinport, refreshed roughly every five minutes. Every value is float-accurate and priced in integer cents, so you can value skins, track cross-market spreads, and read momentum from completed sales without scraping five marketplaces yourself.
Endpoints
The Float + Price API returns the exact float value and best live price for any skin and condition. The Data Feed API returns bulk market rows — supply, floor, median, last sale, and gap percentage — for every tracked item. Both are clean REST JSON.
Pricing
Float + Price API and Data Feed API are $75 each, or $125 for the bundle. A free tier is available to test every endpoint before you commit.
