Description
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.
