> _From schema and cURL to edge-case API tests, pass/fail tracking, and detailed diffs—all automated._

## 📋 Requirements to Get Started

You can use Keploy’s API testing for **any application, in any language**.  
To generate the most valuable and accurate test cases, you’ll need:

### 1. Upload Your OpenAPI Schema (Swagger)

_Why?_  
This gives Keploy a detailed map of your API endpoints, making test generation much smarter and more precise.

### 2. Drop in Your cURL Commands

_Why?_  
Your real-world cURL requests show Keploy how your APIs are actually used, covering positive, negative, and edge cases.

### 3. Make Your App Publicly Accessible (Ngrok Works Great!)

_Why?_  
Keploy needs to interact with your live API endpoints to generate and validate tests. Tools like Ngrok make this easy, even for local apps.
