Does this tool support both YAML and JSON OpenAPI specifications?

Yes. The explorer natively parses both JSON and YAML documents client-side using js-yaml, supporting both Swagger 2.0 and OpenAPI 3.0 / 3.1 specifications.

Are API specifications uploaded or logged on any server?

No. The entire parsing and rendering process occurs 100% locally in your web browser. Proprietary endpoints and internal schemas remain strictly confidential.

Can I generate cURL commands for testing endpoints?

Yes. Each endpoint includes a ready-to-use cURL generator that populates path parameters, query parameters, headers, and request bodies.

Frequently Asked Questions

What formats are supported?

QuickCoderHub OpenAPI Explorer supports OpenAPI 3.0.x, OpenAPI 3.1.x, and Swagger 2.0 specifications formatted in either valid JSON or YAML.

Does this tool resolve external $ref pointers?

It resolves internal references (such as #/components/schemas/... or #/definitions/...) directly in your browser. External URL refs requiring remote network calls are omitted to protect your local privacy.

Can I generate cURL commands for testing?

Yes. The explorer extracts route paths, base URLs, query parameters, headers, and request bodies to synthesize clean copy-paste cURL CLI requests.

Are my API specs uploaded to your servers?

No. 100% of parsing occurs client-side in your browser tab. No spec information, authentication tokens, or schema keys are transmitted over the network.
