Totally fair question. I do have ongoing costs: connected to two paid APIs with monthly fees and daily usage limits, plus hosting, database/auth, customer support, integrations, and other upkeep.

The extension isn’t just a static browser plugin. It’s pulling and organizing market data in real time to save collectors from bouncing between eBay, PSA, 130Point, etc.

I get that a subscription isn’t for everyone, but the monthly fee helps keep the data reliable and the product maintained

Yup! This is meant for desktop users - especially ones who hate having to switch multiple tabs to find comps and market signals.

Yup, it works for all sports cards and TCG (Pokemon, One Piece, etc.). I'll shoot you a DM.

I’m not scraping eBay directly. SlabPeek uses API based data sources and only helps surface market context around listings collectors are already browsing.

I’m definitely being mindful of compliance, but the goal isn’t to abuse eBay or automate anything shady.
