Steam's native trading interface lacks detailed item information (float values, Doppler phases, fade percentages, paint seeds) and trading convenience features. This extension adds that data directly into Steam inventories, trade offers, and market listings, helping traders make informed decisions without leaving the page.

User installs extension, optionally provides their Steam API key in settings. When browsing Steam Community pages (inventories, trade offers, market listings, profiles), the extension injects enhanced UI with pricing data, float values, Doppler phases, profit calculations, and quick-action buttons. The extension fetches price data from api.csgotrader.app and uses the Steam Web API for item details.

Target users: CS2/CS:GO item traders / Steam marketplace buyers/sellers / Skin trading enthusiasts

Source files are heavily minified/bundled, making it difficult to trace exact feature logic for paid vs free gating
The 'premium' keyword hit in 530.bundle.js is ambiguous—could reference a Steam item quality tier (CS2 has 'premium' items) rather than paid extension features
Cannot fully rule out a hidden paywall without exhaustively parsing all 2.8MB+ bundled JS files

Monetization

No paid features detected

The extension is open source (MIT license, GitHub repo linked). No payment/billing/subscription APIs detected. The 'pricing' keyword hits refer to displaying CS2 item market prices, not selling the extension. The 'purchase' hit is a CSS class name (.purchase) for styling marketplace items. The 'premium' hit appears in minified bundle code without clear context of paid gating. No Stripe, Patreon, or payment platform integrations found. No feature gating or upgrade prompts detected in source code.

Login required: Yes
Reason: The extension enhances Steam trading pages (inventories, trade offers, market listings, profiles). Its core features (pricing info, trade profit calculations, inventory management, trade offers) require the user to be logged into Steam (steamcommunity.com). The extension has no login system of its own—it operates on top of the user's existing Steam session. There is also an optional auto-login feature for csgotraders.net (a third-party trading site). A Steam API key is optionally required for advanced features like float values and ban checking.
