Your AI recommended a store. Is it a scam? (Free API, no auth, transparent heuristics)

A developer has released a free, transparent domain reputation checker designed for AI agents that recommend products or stores. The tool, available at marketnow.site, uses heuristic checks to flag suspicious domains and requires no API key or registration. It is positioned as a lightweight alternative to commercial services like WHOISXML and IPQualityScore, offering open CORS and cacheable responses.

AI agents increasingly recommend products, stores, and URLs to users. But when an agent says "this store looks good," there's no automatic check of whether the store is a scam. Commercial services like WHOISXML, IPQualityScore, and CheckPhish sell domain reputation data — but they're paid, require API keys, and are black boxes. You can't see why they flagged a domain. A free domain reputation checker with transparent heuristics. No API key. No registration. CORS open.
