Postman Echo API
Overview
Postman Echo is a free HTTP test server that mirrors back exactly what you send — headers, query parameters, body, cookies, and request method — making it invaluable for debugging API clients and understanding HTTP behavior without needing a real backend. It supports all HTTP methods (GET, POST, PUT, DELETE, PATCH) and several utility endpoints like `/delay/{seconds}` and `/status/{code}` for testing edge cases. No authentication or setup is required.
Beginner Tip
Just send any HTTP request to `https://postman-echo.com/get` (or `/post`, `/put`, etc.) and the server will return a JSON object containing everything it received. This is perfect for testing your `fetch()` or `requests` code before hooking up a real API. Try `curl https://postman-echo.com/get?hello=world` to see the response immediately.

"timestamp": "2025-01-15T10:00:00Z"
}
} Field Reference
args All query string parameters sent with the request, as key-value pairs. headers All HTTP request headers received by the server, including `host`, `user-agent`, and any custom headers you sent. url The full URL of the request as received by the server. data The raw request body (for POST/PUT/PATCH). JSON bodies are returned as objects; plain text as strings. json Parsed JSON body if `Content-Type: application/json` was set, otherwise null. form Parsed form fields if `Content-Type: application/x-www-form-urlencoded` was set. Implementation Example
const url = "https://www.postman-echo.com/";
const response = await fetch(url);
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data); What Can You Build?
