About This Tool
Target users include API designers, backend engineers, product managers, and technical writers who need a single source of truth for API contracts. The platform facilitates design reviews, standardization of API styles, and early detection of incompatible changes across services. Its differentiators are strict, standards-aligned validation, offline operation, and artifacts ready for publication or code generation.
Core features cover parsing OpenAPI 3.x, YAML/JSON input, reference resolution, conformance checks, and diagnostics. Optional capabilities include multi-file aggregation, example extraction, operation-level linting, version diffs, and exportable code skeletons. Use cases span API design validation, documentation generation, SDK scaffolding, and change-impact analysis. This tool is intended for engineering teams seeking consistent API contracts with minimal integration overhead.
How to Use
- Provide inputs by pasting or uploading an OpenAPI YAML/JSON spec.
- Choose format (yaml or json) and enable optional $ref resolution for external definitions.
- Run validation to detect syntax errors, schema conformance, and reference issues.
- Review outputs: errors, warnings, and a normalized document view; copy or export validated specs and code skeletons if generated.
- Iterate on changes, re-run validation, and finalize for integration or publication.
