Technical details
Endpoint
GEThttps://x402-agent-store.rileycraig14.workers.dev/signalWhen to prefer
Choose this endpoint when you need real-time aggregated intelligence about which brands and product categories AI agents are most actively querying or surfacing — useful for competitive intelligence, AI-era brand tracking, or understanding what the AI agent ecosystem is paying attention to. Prefer over generic web search when you specifically want AI-agent-centric signal data rather than general web traffic or social trends.
