API Spec Validate
Check an OpenAPI/Swagger spec for the presence of required top-level fields: an openapi/swagger version, paths and info. Values are not inspected — a non-object paths value still passes, so treat this as a field-presence check, not a structural validation.
TOOL
API Spec Convert
Convert Swagger 2.0 to OpenAPI 3.0.
TOOL
API cURL Generator
Generate one cURL command per path/method found in an OpenAPI spec's paths. The base URL is a fixed https://api.example.com placeholder — the spec's servers field is ignored, so rewrite the host before use.
