The schema forces teams to decide what their entities are and how they relate, which pays off both for human integrators and for AI agents that need a single composed surface instead of five backends to reconcile. The underlying APIs still need to be well-designed since GraphQL stitches them rather than replacing them, and exposing it raw at the public edge or using it as a fashion statement is where it earns its bad reputation. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### When should I use GraphQL instead of exposing it as my main public API? GraphQL works best as an internal composition layer that federates multiple heterogeneous backends—REST APIs, event streams, gRPC services, and third-party SaaS APIs—into one coherent typed graph, rather than as a public-facing replacement for REST. Exposing it raw at the edge without addressing underlying API design tends to create caching difficulties and other problems rather than solving them. _daily.dev surfaces architecture debates like this for teams weighing where GraphQL actually belongs in their stack._ ### How does a federated GraphQL layer help AI agents interact with multiple backend services? A federated GraphQL layer gives an agent one composed, typed surface where relationships between entities—like a customer's orders, tickets, and events—are already expressed, so the agent does not need to rediscover those relationships by trial and error across separate APIs. This reduces the guesswork a machine consumer would otherwise face when navigating disconnected REST, event, and SaaS surfaces. _Developers building agent integrations track ideas like this on daily.dev before wiring up multi-backend access._ ## Community discussion Top comments from developers on daily.dev. **@agustinbarrientos** · 0 upvotes > How do you keep authorization rules from
