eBay Item Feed Service API Gateway for AI Agents

This n8n workflow creates a complete MCP (Multi-Cloud Protocol) server that exposes four essential eBay Item Feed Service API operations to AI agents. It acts as an API gateway, handling requests via a webhook trigger and forwarding them to the eBay API at https://api.ebay.com/buy/feed/v1_beta. Operations include GET /item (Hourly Snapshot Feed), GET /item_group, GET /item_priority, and GET /item_snapshot. AI expressions with $fromAI() placeholders automatically populate parameters, query filters, and headers from agent inputs.

Benefits include seamless integration without custom coding: AI agents connect via a single webhook URL, receiving native eBay responses with full data structures and built-in error handling. It saves significant development time for e-commerce automations, inventory monitoring, and AI-driven market analysis. No need for direct API management—n8n handles authentication, retries, and formatting.

Use cases: Automate inventory checks for dropshipping bots, monitor item priorities for sellers, fetch snapshots for pricing AI models, or integrate into agentic workflows for real-time eBay data. Ideal for commerce platforms, resellers, and AI orchestration tools seeking plug-and-play eBay access.
