Frequently asked questions
Can I try API endpoints here?
No. This editor checks and previews the contract only. It never sends requests to the API described in your file.
Is my OpenAPI file uploaded?
No. The contract is parsed in this browser. YAML support loads a small local parser file on first use; there is no conversion API.
Does this run API calls or check whether a server is online?
No. It never calls the API described by the contract, so it cannot test authentication, responses, or server availability.
Does it validate the complete OpenAPI standard?
No. It checks common version, info, path, operation, response, parameter, and local reference rules. Use an authoritative validator for full schema conformance.
Are remote references downloaded?
No. Only local JSON Pointer references inside the document are checked. URLs and other remote references are reported and never requested.
