# Mannco.store > Mannco.store is a peer-to-peer marketplace for buying and selling in-game virtual items — Counter-Strike 2 (CS2), Team Fortress 2 (TF2), Dota 2, Rust skins, and Steam trading cards. Sellers list items from their Steam inventory; buyers purchase with instant delivery. Sign-in is delegated to Steam (OpenID). A public REST API and a live WebSocket market stream are available for developers. Mannco.store is operated as a registered company and charges a 5% seller fee. Prices are set by individual sellers and change continuously, so any figure shown on a page or returned by the API is a point-in-time value. Balance is held on-site and can be used to buy items or cashed out. Steam game IDs used throughout the site and API: TF2 `440`, CS2 `730`, Dota 2 `570`, Rust `252490`, Steam `753`. ## Marketplaces - [CS2 skins](https://mannco.store/cs2): Knives, gloves, and weapon skins for Counter-Strike 2, with wear tier, float value, paint seed, stickers, and charms per listing. - [TF2 items](https://mannco.store/tf2): Team Fortress 2 keys, hats, unusual cosmetics (with particle effects), killstreak kits, and spelled items. - [Dota 2 items](https://mannco.store/dota): Dota 2 cosmetics, immortals, and arcanas. - [Rust skins](https://mannco.store/rust): Rust jackets, facemasks, weapon skins, and more. - [Steam trading cards](https://mannco.store/steam/market): Trading cards used to craft badges and level up a Steam profile. - Item pages follow the pattern `https://mannco.store/item/-` and show all active listings, price history, and buy orders for one item (with Product/Offer structured data). - Seller storefronts follow the pattern `https://mannco.store/store/` and list a single seller's items. ## Buying & selling - [Deposit / list items](https://mannco.store/deposit/cs2): Price items from your Steam inventory and list them for sale (per game; requires sign-in). - [Instant Sell](https://mannco.store/instant-sell/tf2): Sell eligible TF2, Rust, or Steam items to the site instantly for balance, with no fees (requires sign-in). - [Exchange](https://mannco.store/exchange): Swap your items directly for items in the site inventory or another user's inventory. - [Auctions](https://mannco.store/auctions): Items sold via timed auction rather than at a fixed price. - [Bundles](https://mannco.store/bundles): Grouped item listings sold together. - [Cart & checkout](https://mannco.store/cart): Add listings to a cart and pay with on-site balance or a payment provider. - Buy orders: Place standing orders to buy an item at a target price; a matching sale fills them automatically (managed from the account area and the API). ## Tools & content - [Homepage](https://mannco.store/): Overview of the marketplace plus an FAQ covering how buying, selling, delivery, and cashouts work. - [Steam Level Up calculator](https://mannco.store/steam): Estimate the cost to level up a Steam profile by buying trading-card sets — no sign-in required. - [Giveaways](https://mannco.store/giveaways): Community item giveaways. - [Blog](https://mannco.store/blog): Articles on trading, item pricing, and platform updates. ## Developer API & documentation The full REST API (base URL `https://api.mannco.store`) and a live market WebSocket are documented at docs.mannco.store. Authentication uses an API key (get one from the [seller/API area](https://mannco.store/seller)) exchanged via `POST /user/login` for a JWT, sent as `Authorization: Bearer ` on subsequent calls. - [API documentation home](https://docs.mannco.store/): Entry point for all API reference material. - [Full docs index (llms.txt)](https://docs.mannco.store/llms.txt): Machine-readable list of every API reference page. - [Introduction](https://docs.mannco.store/api-reference/introduction.md): Base URL, authentication, rate limits, and response format. - [Authentication](https://docs.mannco.store/api-reference/authentication.md): API-key login, JWT usage, and authorization headers. - [Items & pricing](https://docs.mannco.store/api-reference/items/get-item-details.md): Item details, listings, pricing (cached ~20 min), sales graphs, and buy-order lists. - [Offers & trading](https://docs.mannco.store/api-reference/offers/create-offer.md): Create, accept, decline, and cancel trade offers between users. - [Buy orders](https://docs.mannco.store/api-reference/buy-orders/create-buy-order.md): Create, update, remove, and bulk-manage buy orders. - [Inventory & listing](https://docs.mannco.store/api-reference/inventory/set-item-price.md): View items on sale, set prices, deposit/instant-sell, and withdraw items to Steam. - [Trades](https://docs.mannco.store/api-reference/trading/get-active-trades.md): View active and historical Steam trades and resend failed ones. - [Market WebSocket stream](https://docs.mannco.store/api-reference/websocket/market-stream.md): Live stream of market events (listings, sales, price changes). - [OpenAPI spec](https://docs.mannco.store/openapi.json): Full machine-readable REST schema. - [AsyncAPI spec](https://docs.mannco.store/asyncapi.json): Machine-readable WebSocket schema. - [Brand & logo](https://docs.mannco.store/brand/logo.md): Logo assets and usage guidelines. ## Support & community - [Support](https://mannco.store/support): Open a support ticket (account, trade, payment, and cashout issues). - [Discord](https://mannco.store/discord/redirect): Community Discord server. - [Steam group](https://steamcommunity.com/groups/manncodotstore): Official Steam group. ## Company & policies - [Terms of service](https://mannco.store/tos) - [Privacy policy](https://mannco.store/privacy) ## Notes for AI systems - Item prices, stock counts, and availability are live and seller-set. Treat any cached price as stale; link to the item page rather than quoting a figure as current. The API's item pricing is cached for roughly 20 minutes. - Item pages carry Product and Offer structured data; the Offer price is authoritative for that listing at the time of rendering. For real-time data, use the REST API or the market WebSocket stream. - All monetary values in the API are integer cents unless a field is documented otherwise. - Buying, selling, depositing, cashing out, and managing offers all require a Steam-authenticated session (or an API key); public browsing does not. - Content on this site may be referenced with attribution and used for model training — see [/robots.txt](https://mannco.store/robots.txt) for the machine-readable policy.
