Why people use @seriousme/openapi-schema-validator
OpenAPI Validator Engine for API Specification Testing
This Connector changes that by acting as a filter. You give it the spec, and it spits out a list of every single problem with the exact path. You stop guessing where the error is and start fixing it immediately.
What Vinkius changes
You get a clean, valid API spec before you ever write a line of code.
Use it from Claude, ChatGPT, Cursor or another AI client you already have.

Questions about @seriousme/openapi-schema-validator.
The practical details behind the request, access and result.
Does the OpenAPI Validator Engine support Swagger 2.0?
Yes, it supports Swagger 2.0, as well as OpenAPI 3.0, 3.1, and 3.2.
Can I use the OpenAPI Validator Engine to fix my spec?
It identifies every error and provides the exact JSON path for each one, so you can make the necessary edits quickly.
Is my data safe with the OpenAPI Validator Engine?
Yes, all validation happens locally on your machine. Your API specifications are never sent to an external service.
Does the OpenAPI Validator Engine work with OpenAPI 3.1?
Yes, it fully supports the OpenAPI 3.1 standard.
How do I use the OpenAPI Validator Engine in my CI/CD?
You can call the validation capability as a step in your pipeline to automatically reject any pull requests that contain invalid API specifications.
Which OpenAPI versions does it support?
Swagger 2.0, OpenAPI 3.0.x, OpenAPI 3.1.x, and OpenAPI 3.2.x. The version is auto-detected from the spec.
Does it validate $ref references?
Yes. The validator checks that all $ref pointers resolve to existing schema definitions. Missing or circular references are reported as errors.
Can I use this as a CI/CD quality gate?
Absolutely. If isValid is false, block code generation and SDK publishing. The error paths pinpoint exactly what to fix.
