Custom JSON Endpoint Generator helps you create a working JSON endpoint in seconds—ideal for frontend development, demos, QA, and integration testing.

Paste a JSON payload, choose an HTTP method and status code, and instantly get a shareable URL that returns the exact response you defined. It's perfect when you need a quick mock API without spinning up a backend, deploying servers, or writing boilerplate code.

Use it to prototype UI flows, test webhooks, simulate error responses, or share example APIs with teammates and clients.
