Browser extension that enriches Funda.nl (Dutch real estate platform) property listings with historical price data and listing history transparency

Home buyers in the Netherlands cannot easily see if a property has been previously listed, re-listed, or had price changes on Funda.nl. Real estate agents may relist properties as 'new' to reset buyer attention. This extension reveals hidden price history and listing history that agents don't voluntarily disclose.

User browses Funda.nl → extension auto-detects listing pages via URL pattern → background script POSTs to api.walterliving.com/hunter/lookup → response cached by Funda ID → popup shows price history timeline and listing count → icon changes to alert if property was re-listed → user can click to view/create a Walter Living valuation report on external site

Target users: Dutch home buyers actively searching on Funda.nl / People who want transparency in the Dutch real estate market

The destination service (walterliving.com) may have its own paid features or require accounts for property valuation reports, but this is outside the extension's scope
No storage, identity, or billing-related permissions exist in the manifest, confirming no in-extension payment or login infrastructure

Monetization

No paid features detected

The extension itself has no payment UI, no subscription checks, no billing API calls, no feature gating, and no premium/free tier distinctions. All core functionality (price history timeline, listing count detection, icon state changes) is available to every user. The extension links out to walterliving.com for 'woningwaarderapport' (property valuation reports) which may be a paid service on the destination site, but the extension does not gate any of its own features behind payment.

Confidence: 88
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension makes unauthenticated API calls to api.walterliving.com/hunter/lookup (background.js:88) with no auth headers or tokens. There is no login UI, no account creation flow, no credential storage, and no authentication checks anywhere in the codebase. The 'token' reference on line 193 of betrapdemakelaar.js refers to json.report.token (a report identifier from the API response), not an authentication token. The core workflow—viewing price history for Funda.nl listings—works without any login.
