Helps users verify whether the current selling price of Gunpla on third-party sites (Amazon, Mercari, etc.) is fair by comparing it against the official Bandai Hobby Site price, especially useful during shortages or resale price inflation.

User navigates to a Gunpla product page (e.g., Amazon) → clicks extension icon (or selects text and clicks icon) → extension sends page title/selected text to gunpla-database.doc-sin.life API → API returns matching products with official Bandai prices → popup displays a table with product name, price, and availability status.

Target users: Gunpla hobbyists in Japan / Gundam model collectors / Shoppers looking to verify fair pricing

The extension relies on an external API (gunpla-database.doc-sin.life) whose availability and data accuracy are not verifiable from source code alone.
The API endpoint may have rate limits or downtime not visible in static analysis.
Some features mentioned in the store description (e.g., '再出荷日' reshipment date) appear to be commented out in the current code version, suggesting they may be disabled or removed.

Monetization

No paid features detected

No evidence of paid features, subscription gates, payment platforms, or upgrade prompts in the extension code. The extension is free and displays Bandai official prices (定価) for Gunpla models. The keyword 'pro' found in popup.js is a false positive from substring matches in variable names like 'products', 'product', 'product_url', not related to paid tiers.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension performs all its functions without requiring any user authentication. It fetches data from a public API (gunpla-database.doc-sin.life) using only the page title or selected text as input. No login UI, token handling, or account creation flows exist in the source code.
