If you are building a trading bot, a price tracker or a Discord bot for CS2 skins, the first question is where the data comes from. Marketplaces differ a lot here: some publish their whole price list for anyone, some offer a full trading API with your own keys, and some have nothing public at all.
Free public price lists
A few marketplaces publish the lowest price of every item they sell, with no key and no account. They are the easiest place to start:
- Skinport: a public items endpoint lists every item with its lowest, median and highest price. It answers Brotli-compressed responses only, so your HTTP client must accept them.
- Market.CSGO: one JSON file with the price of everything for sale, in USD.
- LIS-SKINS: a public JSON export of its whole CS2 market.
- Waxpeer: a public price list of every item, prices in thousandths of a dollar.
- DMarket: its aggregated prices request answers without a key, giving the best offer and best buy order of up to 100 items at a time.
These lists cover stickers, agents, cases and more, not just weapon skins. Each one only covers its own marketplace, and each has its own format, units and naming quirks (Waxpeer, for example, writes Doppler phases into item names).
Trading APIs with your own keys
- DMarket: a full trading API signed with your own Ed25519 keys, made under Settings → Trading API: list and reprice offers, place and remove buy orders (DMarket calls them targets), read your inventory and balance.
- Market.CSGO: an API key from your account lets you list items, change prices and place buy orders. It deletes keys that send more than 5 requests a second, so space your requests.
- CSFloat: searching listings needs an account; an API key comes with it.
No public API
Buff163 and YouPin answer their data only to signed-in accounts, and some marketplaces, like cs.money, sit behind bot protection. For these, the practical option is a price aggregator.
Every marketplace from one API
Calling many marketplaces yourself means many formats, rate limits and outages to handle. Our price API returns the lowest listing of every tracked item on 22 marketplaces in one format, Buff163, YouPin and CSFloat included. Read the price API guide for examples, give it to an AI agent, or compare prices by hand on the prices table.
