Problem: sports card resellers and grading service operators price cards by manually checking completed eBay listings and PWCC auction results, a slow process that misses recent comps and introduces pricing error on inventory they buy, hold, and flip. Named product: SoldComps for Sports Cards, a real-time sold price API. Solution: a single endpoint that returns completed eBay and PWCC sale prices filtered by player, year, and grade, so a reseller or grading shop can look up accurate, recent sold values programmatically instead of eyeballing listings. MVP: ingest completed eBay sold listings and PWCC auction results, normalize them into a player-year-grade schema, and expose a REST API returning recent sale prices, counts, and date ranges. A thin dashboard for manual lookups broadens the early user base beyond developers. Revenue: tiered monthly SaaS subscriptions by API call volume, with higher tiers for grading operators who run bulk valuations. GTM: direct outreach to the 6-figure card business operators visible across YouTube, plus placement in hobby communities where pricing accuracy is a daily pain. Growth loops: resellers who integrate the API into their listing workflows become sticky, and the dashboard lookups double as a top-of-funnel lead source that converts manual users into API subscribers.

The only tracked keyword, ecommerce tools, has low volume (390) and sharp decline (-70.8%), so SEO on generic terms is not a viable primary channel. The real signal is community depth: a cluster of YouTube content around sports card investing, finding card values, flipping cheap versus expensive cards, and running six-figure home businesses. This indicates an engaged operator audience actively grappling with pricing, which maps directly to the product's value proposition and points to creator and community channels over paid search.
