It covers very completely different instruments.Some APIs return protocol metrics like complete worth locked. Others learn a single pockets's positions throughout lots of of protocols. A number of execute swaps. One layer streams listed blockchain occasions. One other delivers oracle costs to sensible contracts instantly.The mistaken selection prices weeks of integration work. The fitting one matches your particular construct, not another person's guidelines.In apply, the choice comes down to 3 questions:

What sort of DeFi information do I would like? (Protocol-level metrics, per-wallet positions, or reside worth feeds?)


How will or not it's delivered? (REST polling, WebSocket streams, or AI-ready MCP servers?)


What's the integration scope? (One endpoint, or a {custom} indexer wired into the backend?)
