# Skinbase > Skinbase compares Counter-Strike 2 (CS2) item prices across 30+ marketplaces and provides item catalogs, market analytics, and trade-up and container ROI tools. Skinbase combines a public CS2 item catalog with marketplace comparison, buy-order data, price and sales history, liquidity scores, trade-up research, inventory valuation, price alerts, and a subscription REST API. It helps players, traders, and developers research provider-specific prices instead of treating all markets as one blended price. Brand: Skinbase. Website: https://skinbase.io. API base URL: https://api.skinbase.io. Last reviewed: 2026-10-25. This is a maintained reference, not a live price feed. English pages use unprefixed URLs; localized pages use language prefixes such as /pl. The English blog is at /blog. The interactive Compare workspace requires Steam sign-in; its public landing page describes the available features. Prices, availability, and historical coverage vary by provider and item; verify the current listing, fees, and trade restrictions before acting. Data API requests require an active eligible subscription and the `x-api-key` header. Use `Accept-Encoding: gzip` with a client that decompresses gzip; compression support is required by the history, sales-statistics, and market-cap endpoints. History bounds use Unix milliseconds. Request-span limits do not guarantee that every item has that much history. ## Start here - [Full Skinbase reference](https://skinbase.io/llms-full.txt): Product workflows, provider IDs, API access, request and response semantics, examples, and common questions. - [API documentation](https://skinbase.io/api-documentation): Human-readable endpoint descriptions and examples. - [Interactive API reference](https://api.skinbase.io/docs): Explore the public REST API schema. - [OpenAPI JSON](https://api.skinbase.io/openapi): Machine-readable endpoint and parameter definitions. - [API plans](https://skinbase.io/api-pricing): Current subscription prices, billing options, and plan comparison. ## Price comparison and item research - [Skinbase](https://skinbase.io/): Overview of CS2 item comparison and research tools. - [Browse items](https://skinbase.io/browse): Search and filter the item catalog, then open item pages for marketplace prices and item details. - [Compare marketplaces](https://skinbase.io/compare): Compare workflow, marketplace and item filters, fee guidance, and Steam sign-in for the interactive workspace. - [Marketplace directory](https://skinbase.io/cs2-marketplaces): Marketplace information, fees, payment methods, and reviews. - [Weapons](https://skinbase.io/weapons): Browse skins by weapon category. - [Collections](https://skinbase.io/collections): Explore skin collections and their contents. - [Cases](https://skinbase.io/cases): Explore CS2 cases and their contents. - [Capsules](https://skinbase.io/capsules): Explore sticker capsules and their contents. - [Packages](https://skinbase.io/packages): Browse souvenir packages and their contents. ## Calculators and market analytics - [ROI analysis](https://skinbase.io/roi): Explore estimated returns for containers and other CS2 item sources. - [Armory ROI](https://skinbase.io/roi/armory): Compare estimated returns for Armory rewards. - [Collection ROI](https://skinbase.io/roi/collections): Explore estimated returns by collection. - [Sticker ROI](https://skinbase.io/roi/stickers): Explore sticker capsule return estimates. - [Operation ROI](https://skinbase.io/roi/operations): Explore operation-related return estimates. - [Trade-up calculator](https://skinbase.io/tradeup): Build trade-up contracts and inspect possible outcomes and probabilities. - [Trade-up Finder](https://skinbase.io/tradeup/finder): Search for trade-up candidates using item and profitability filters. - [Trade-up database](https://skinbase.io/tradeup/database): Browse community-shared recipes, refresh prices, and open recipes in the calculator. - [Market capitalization](https://skinbase.io/cs2-marketcap): Explore CS2 market capitalization data. - [Price indexes](https://skinbase.io/indexes): Follow normalized price performance for the broader market, categories, and rarities. - [Inventory tracker](https://skinbase.io/inventory): Look up Steam inventories and explore item valuations and stored value history. - [Tier list builder](https://skinbase.io/tierlist): Arrange CS2 items into custom tiers and share a ranking. ## Data coverage and interpretation - [Marketplace coverage](https://skinbase.io/cs2-marketplaces): Sources include BUFF163, YouPin, CSFloat, Skinport, Steam, DMarket, Market.CSGO, C5Game, EcoSteam, SkinBaron, Waxpeer, ShadowPay, and others.
