Axie Infinity marketplace does not show important hidden information like breed count, HP, speed, morale, purity percentage, and hidden genes on listing cards. Players need this data to make informed breeding and trading decisions.

User installs extension → enables via popup checkbox → navigates to marketplace.axieinfinity.com → extension content script monitors DOM mutations → when Axie cards load, extension fetches detailed Axie data via Axie Infinity's GraphQL API → decodes 512-bit genes → injects breed count, HP, speed, morale, and purity stats onto each card → hovering reveals hidden genes

Target users: Axie Infinity players / Axie NFT traders / Axie breeders looking for genetic information / Axie Infinity marketplace users

Cannot verify behavior on actual Axie Infinity marketplace pages as this is offline code analysis
The 'More tools' link to freakitties.github.io/axie/ was not analyzed - external web app may have its own features/login
Axie Infinity marketplace itself may have changed its GraphQL API since last extension update (Aug 2022)

Monetization

No paid features detected

The extension is completely free with no paid features. The codebase contains no payment processing (no Stripe, PayPal, or any billing APIs), no subscription logic, no premium/upgrade prompts, and no feature gating. All features (breed count display, HP/speed/morale stats, purity calculation, hidden gene display) are available to all users. The 'pro' keyword hits were all false positives - 'PROBABILITIES' is a gene probability constant, 'profile' refers to marketplace profile URLs, and 'Promise' is a JavaScript construct. The extension is open source (LICENSE.txt present) and there is a link to 'More tools' at freakitties.github.io/axie/ but no payment is embedded in the extension.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension does not implement any login or authentication system. The 'account' keyword hits in contentScript.js (lines 324-352) refer to parsing the Axie Infinity wallet address (Ronin address) from the marketplace URL to identify which player's Axies to display - not user authentication. The extension operates purely as a content script on marketplace.axieinfinity.com, reading publicly available data. While the destination service (Axie Infinity marketplace) may require login to access inventory pages, the extension itself does not gate any functionality behind authentication.
