Track NFT listings, offers, orders, and trait-based pricing in real time! This workflow integrates OpenSea API, AI-powered analytics (GPT-4o-mini), and n8n automation to provide instant insights into NFT trading activity. Ideal for NFT traders, collectors, and investors looking to monitor the market and identify profitable opportunities.

How It Works

A user submits a query about NFT listings, offers, or order history. The OpenSea Marketplace Agent determines the correct API tool:

– Retrieve active NFT listings for a collection.
– Fetch valid offers for individual NFTs or entire collections.
– Identify the cheapest NFT listings by collection or token ID.
– Track the highest offer made for a single NFT.
– Access detailed order history for a transaction.

The OpenSea API (requires API key) is queried to fetch real-time data. The AI engine processes and structures the response, making it easy to interpret. The NFT marketplace insights are delivered via Telegram, Slack, or stored in a database.

What You Can Do with This Agent

🔹 Find the Best NFT Listings → Retrieve the cheapest available listings in any collection.

🔹 Track Offers on NFTs → See all active offers, including highest bids.

🔹 Analyze Collection-Wide Market Data → Compare listings, offers, and sales activity.

🔹 Retrieve Order Details → Search by order hash to check buyer, seller, and transaction status.

🔹 Fetch NFT Trait-Based Offers → Identify rare traits that receive premium bids.

🔹 Monitor Multi-Chain Listings → Works across Ethereum, Polygon (Matic), Arbitrum, Optimism, and more.
