Why Use an Online API Tester?
Debugging APIs often involves switching context between your code and tools like Postman or Curl. Our online tester allows you to quickly verify endpoints without installing heavy desktop applications.
Key Features
- CORS Bypass: Requests are proxied through our server, so you don't need to worry about Cross-Origin Resource Sharing policies during testing.
- JSON Pretty Print: Messy JSON responses are automatically formatted for readability.
- Header Inspection: View raw response headers to debug caching, security, and cookie issues.
- Status Codes: Instantly see if your API returns 200, 404, or 500 errors.
