The good reasons are decoupling, load-leveling, fan-out, and durability. The bill is eventual consistency, added latency, operational burden, and harder debugging. And a clear account of when you should not reach for it at all.

API-side levers from horizontal scale and caching to async and backpressure, and client-side levers from the CDN to optimistic UI. Each one gets a line on what it buys and what it costs. This is the map; the API and UI series are the territory.
