FAQPage Schema
How do I generate an OpenAPI 3.1 specification for REST and GraphQL APIs?

To generate an OpenAPI 3.1 specification, you can use this Skill to streamline API architecture, resource modeling, and versioning. It relies on Python libraries like pydantic and openapi-generator to produce the required specification files.

What is the best way to plan API versioning and handle backward compatibility?

Planning API versioning requires defining deprecation and backward-compatibility strategies. This Skill provides specific guidance on structuring API versioning, ensuring smooth transitions while maintaining stable OpenAPI 3.1 specifications for your REST or GraphQL endpoints.

How do I model resources and relationships when designing API architecture?

Modeling resources involves identifying key entities, their relationships, and supported operations. This Skill offers structured guidance on resource modeling within your API architecture, ensuring your OpenAPI 3.1 specifications accurately represent your data structures.

Do I need Python libraries to set up a mock server for OpenAPI specifications?

Yes, you need Python libraries including openapi-generator and requests to set up a mock server. The Skill requires these dependencies to facilitate OpenAPI specification generation and mock server setup for testing REST and GraphQL APIs.

Can I use redocly-cli to validate OpenAPI 3.1 specifications created with this approach?

Yes, redocly-cli is included as a dependency to support OpenAPI 3.1 specifications created through this process. It works alongside openapi-generator and pydantic to validate and maintain the quality of your generated API documentation.

What strategies help with API error handling and pagination patterns?

Effective API error handling and pagination patterns are planned during API architecture design. This Skill streamlines the creation of these strategies within your OpenAPI 3.1 specifications, ensuring consistent resource modeling and error handling across endpoints.
