Standardize REST API error responses by formatting failures as RFC 9457 Problem Details. This provides a consistent error shape, improving API observability and client error handling across services.

OpenAPI design-first API development involves drafting an OpenAPI 3 contract before writing code. This approach guides API development and documentation, ensuring the implementation matches the standardized contract.

Apply path-based versioning and kebab-case routing in ASP.NET Core APIs by enforcing these conventions through an OpenAPI 3 contract. This ensures predictable resource routing and consistent URI paths across services.

Yes, this approach supports default pagination using _page and _size query parameters. It enforces a consistent paginated response shape to improve API usability and reliability for large data sets.

Yes, you can integrate with ASP.NET Core tooling like Swashbuckle to generate and explore OpenAPI docs. This validates that your design-first contracts align properly with the implemented JSON payloads and status codes.

The best way to standardize REST API design across services is enforcing an OpenAPI 3 design-first contract. This dictates path-based versioning, kebab-case naming, default pagination, and RFC 9457-compliant error handling.
