What is an online API client

An online API client helps developers send HTTP requests, test endpoints, inspect status codes and headers, search response bodies, and capture working request examples without switching applications.

Request data is only sent to the endpoint you choose when you run an API request.

FAQ

Can I use this API client online without installing software?

Yes. The API client runs in your browser and can send requests through browser fetch or the included proxy flow.

Can I import a cURL command?

Yes. Paste a cURL command to populate the method, URL, headers, and body fields.

Can it generate API documentation?

Yes. The current request can be exported as Swagger or OpenAPI JSON and YAML.

What is the difference between browser fetch and proxy mode?

Browser fetch follows normal browser security rules such as CORS. Proxy mode is there for cases where the target API needs a same-origin helper during local testing.

Does Aruvix store my auth headers or tokens?

No server-side storage is used for your request details. Treat sensitive tokens carefully, especially on shared devices or shared browser profiles.

Can I reuse variables across requests?

Yes. Variables help you swap hosts, IDs, and tokens without rewriting the whole request every time you test an endpoint.

Can it replace Postman or Insomnia?

For quick browser-based API checks, cURL handoff, response inspection, and OpenAPI snippets, yes. For team workspaces and synced collections, keep using a dedicated API platform.
