Built an eBay scraper that rips at 15 req/sec (thanks to Reddit help). What free Shopify plugin do you guys want me to build with it?

Hello guys, I've been working on an eBay scraper which, thanks to Reddit communities, got this far. The backend is completely re-architected and now it's flying—ripping through comps and data at around 15 requests per second (check out the video above to see the speed).
While building and optimizing this, it got me thinking about the Shopify ecosystem. Most apps that pull marketplace data or handle pricing charge heavy monthly subscriptions.
Screw that. I want to build a** **Shopify plugin powered by this scraper engine and give it away free. No paywalls, no subscriptions, no credit cards.
So what kind of free Shopify plugin do you guys actually need or wish existed? Should it be a dynamic repricer, an instant trade-in widget, a market competitor spy, or something else?

What pricing/comp tool do you actually use, and how much are you putting on monthly fees?

Hello guys, I've been working on an eBay scraper which, thanks to Reddit communities, got this far,
While building this personal project , it got me thinking: what apps or tools are you guys currently using to check eBay comps, and how much are you paying for them? I see so many tools charging $20 to $50+ a month just to pull basic 90-day sold data or lock features behind paywalls.
Screw that. As a thank you to the Reddit communities who helped me build this, I’m keeping my app for free to No paywalls, no subscriptions, no credit card required.
Drop a comment telling me what overpriced apps you're currently using, or what category you want me to test next with the 15 req/sec scraper. So I can know what to build
