This is a meta-layer for API discovery that helps AI agents figure out which APIs to use based on intent rather than hardcoded integrations. Instead of manually connecting to specific services, you describe what you want to accomplish and it suggests relevant APIs that match your goal. Think of it as a routing layer that sits between your agent's objective and the dozens of potential APIs that could fulfill it. The source doesn't detail specific API catalogs or selection algorithms, but the concept addresses a real pain point: as agents get more capable, manually wiring up every possible integration doesn't scale. Reach for this when you're building agents that need to dynamically choose between multiple APIs or discover new ones based on user intent.
