CompSniper

CompSniper helps people make faster, better resale and sourcing decisions with real completed eBay marketplace data. Search completed sales for a product, receive compact listing rows with title, sold price, shipping, condition, sold date, seller, and URL, and get cleaned price intelligence including median, p25, p75, realistic ranges, sample size, currency, and raw-versus-cleaned evidence. Compare multiple products or the same product across eBay marketplaces. For deeper research, Max Mode runs an asynchronous sold-comps sweep and provides a signed CSV export when complete. The connector uses OAuth 2.0 so each user authorizes their own CompSniper account and quota. It reads public marketplace sold data through CompSniper's first-party API and is not affiliated with eBay. It does not access a user's unrelated files, full conversation, Claude credentials, or OpenAI credentials.
