• Marketplace Coverage: SIH recognizes and enhances Steam item trading pages across a growing list of supported third-party marketplaces, so your inventory data stays useful wherever you trade.

Some features require you to be logged into Steam.

Permissions Required:

• Access to Steam Sites (://.steampowered.com/* & ://steamcommunity.com/): Reads your own inventory and displays item prices, valuation, and trade status directly on these pages.
• Access to Gainskins API (://sih.gainskins.com/): Retrieves public pricing data used to show accurate prices and stats for items in your inventory.
• SteamCharts Access (://steamcharts.com/): Retrieves public game statistics and currency conversion rates used to display accurate pricing for your inventory items.
• Market.CSGO Access (://market.csgo.com/): Used only if you enable this feature in settings, to let you create trade offers for items in your inventory.
• SteamRep Access (://steamrep.com/): Retrieves public profile flags (trade ban, VAC ban, community ban) for the Steam profile you're viewing, to help you assess trading safety.
• Broad host access (all URLs): Used to detect and enhance Steam item trading pages across third-party marketplaces beyond the domains listed above. The list of supported marketplaces grows over time based on user demand, so a fixed domain list would break functionality on new sites. SIH only activates its inventory/pricing display on pages it recognizes as Steam-item-trading pages, and does not collect or transmit data from unrelated websites.
• notifications: Notifies you about trade status and price changes for items in your own inventory.
• alarms: Periodically refreshes the prices and trade status of items in your inventory in the background.
• storage: Stores your display preferences and settings locally.
• unlimitedStorage: Caches your inventory and price data locally so it loads quickly, without hitting the default browser storage limit.
• background: Keeps price and trade-status information for your inventory up to date.
• webRequest / declarativeNetRequest / declarativeNetRequestFeedback: Used to correctly route and verify requests to the Steam and marketplace endpoints above, needed to load your inventory, prices, and trade status without sending your data through our own servers.
• cookies: Reads your existing Steam login/session status (read-only), so you don't need to log in again to see your own inventory.
• activeTab: Displays prices and item details for your inventory directly on the Steam page you have open.
• management: Detects other installed Steam-related extensions that inject content into the same pages, to avoid conflicting UI elements.
