and deep research** into NFT market trends, asset tracking, and real-time trading insights.  \n\nIt leverages **three powerful agent tools** to provide **actionable insights and decision-making intelligence**:  \n1. **Marketplace Agent** \u2013 Fetches **listings, orders, offers, and trait-based pricing data**.  \n2. **Analytics Agent** \u2013 Retrieves **NFT collection statistics, transaction histories, and market analytics**.  \n3. **NFT Agent** \u2013 Gathers **detailed metadata, ownership details, and payment token data**.  \n\n\ud83e\udde0 **This AI system can process multiple tools together, conduct research between datasets, and synthesize powerful responses to user queries.**  \n\n---\n\n## **\ud83d\udee0 Actionable Insights & Multi-Step Queries**\nThe agent can **combine** multiple tools, process collected data, and execute deep research for **smarter responses**.  \n\n\ud83d\udd39 **How this works**:\n- \ud83c\udfdb **Compare multiple collections** _(e.g., floor price, sales volume)_  \n- \ud83c\udfaf **Track NFT flipping trends** _(e.g., which wallets buy/sell the most)_  \n- \ud83d\udd25 **Identify undervalued NFTs** _(e.g., listings below average trait value)_  \n- \ud83d\udcca **Aggregate sales data over time** _(e.g., 7-day vs. 30-day collection trends)_  \n- \ud83d\udc65 **Analyze whale movements** _(e.g., track large NFT purchases)_  \n- \ud83d\udca1 **Predict market shifts** _(e.g., sudden spikes in buy offers)_  \n\n\ud83d\udce2 **Example Action Queries:**  \n- _\u201cFind me the top 5 most undervalued Azuki NFTs based on recent sales.\u201d_  \n- _\u201cCompare the last 3 months of trading volume between Moonbirds and CloneX.\u201d_  \n- _\u201cTrack all wallets that recently sold a Bored Ape Yacht Club NFT.\u201d_  \n-
