Blocks unwanted surprises when buying or selling CS:GO & CS2 items on Steam Market or Inventories with Csfloat Market Checker, a simple and easy-to-use extension that displays float values, paint seeds, and more. Lets you make informed decisions by providing essential information to serious collectors and traders. Benefits most those who frequently purchase or sell rare items online.

Overview

CSFloat Market Checker uses the dedicated CS Float (formerly CSGO Float) API to allow you to retrieve the float values, 3d models, and screenshots of market items directly from the page!

GitHub: https://github.com/csfloat/extension

Note: Items queried will be ranked on FloatDB (csfloat.com)

Features:

* Allows verification for trades on CSFloat Market
* Allows you to retrieve the float, paint seed, and float rank of any market or inventory item
* Allows you to fetch the 3D model and screenshot of the item directly on the page
* Fetches all floats on the page fast and automatically on page load
* User-definable filters to highlight items with low floats or certain paint seeds
* Shows market item stickers at a glance and their wear
* Change the amount of items on the page up to 100

Compatibility:
* This extension has been tested to work with Steam Inventory Helper and Enhanced Steam
* Since this extension doesn't hook and modify HTTP headers to bypass steamcommunity.com CSP, it should have greater compatibility with other extensions.
