API service contracts identify independently deployable APIs and document their endpoints, data contracts, and communication patterns. This generates an authoritative API surface description covering service catalogs, endpoint inventories, and inter-service sequence diagrams.

Yes, you can generate a Mermaid sequence diagram illustrating synchronous and asynchronous calls alongside failure and retry scenarios. This service communication diagram maps core request flows across independently deployable services.

The best way to distinguish gateway-level DTOs from service-level domain models is by generating explicit contract documents that separate them. This distinction supports API governance by clarifying external API surface boundaries from internal domain logic.

Yes, this approach captures management and observability endpoints by producing a dedicated catalog. It explicitly includes references to custom metrics and documents the security posture at the API layer for complete observability coverage.

Create an OpenAPI reference by scanning your codebase to inventory independently deployable APIs. The process outputs OpenAPI references alongside gateway-level DTOs and service-level contracts to establish an authoritative API surface description.
