Test API Endpoint — Free Sample REST API for Testing | Send Web Request

Copy a URL, paste it into your code, and you get the answer below. Every endpoint is free, needs no key, and works straight from the browser.

Request tools

POSThttps://sendwebrequest.com/echo

Sends your request back to you — method, headers, query, and body. Works with any method.

{
  "method": "POST",
  "path": "/echo",
  "query": {},
  "headers": {
    "content-type": "application/json"
  },
  "body": "{ \"hello\": \"world\" }"
}

GEThttps://sendwebrequest.com/status/404
Returns any status code you ask for. Try /status/500, /status/403, and so on.
```
{
  "status": 404,
  "message": "Not Found"
}
```
GEThttps://sendwebrequest.com/delay/2
Waits, then answers. Good for testing loading states. Up to 5 seconds.
```
{
  "delay": 2,
  "message": "Waited 2 seconds"
}
```

When you're wiring up fetch, axios, or React Query, you need a real endpoint to hit — one that returns predictable JSON, lets you force error codes, and doesn't need an API key. Send Web Request hosts a free, CORS-open test API you can call from any browser or codebase. Get sample data, echo your request back, return any status code, or add a delay to test loading states.

What is a test API endpoint?

A test API endpoint is a public URL that returns predictable data so you can build and debug a client without a real backend. You point your fetch or axios call at it, confirm your request is shaped correctly, and check how your UI handles the response. Because it's CORS-open, you can call it straight from browser JavaScript — no proxy, no key, nothing to install.

The endpoints

Four families of endpoints cover the common testing needs. All accept any HTTP method and are open to cross-origin requests:

GET  https://sendwebrequest.com/mock/users/1   → sample JSON
ANY  https://sendwebrequest.com/echo            → your request, reflected back
GET  https://sendwebrequest.com/status/404      → responds with that status code
GET  https://sendwebrequest.com/delay/3         → responds after ~3 seconds

Try GET /mock/users/1 →

Get sample JSON data

The /mock endpoints serve fake but realistic users, posts, and todos. Request a whole collection or a single item by id. Nothing is stored — the same URL always returns the same data.

GET https://sendwebrequest.com/mock/users
GET https://sendwebrequest.com/mock/users/1
GET https://sendwebrequest.com/mock/posts
GET https://sendwebrequest.com/mock/todos?limit=5

Try GET /mock/posts →

Test fetch

Drop the endpoint straight into a fetch call. It returns JSON with an application/json content type, so response.json() just works:

const res = await fetch("https://sendwebrequest.com/mock/users/1");
const user = await res.json();
console.log(user.name); // "Ada Lovelace"

Try it in the browser →

Test axios

Same endpoint, with axios:

import axios from "axios";

const { data } = await axios.get(
  "https://sendwebrequest.com/mock/posts?limit=3"
);
console.log(data.length); // 3

Test React Query

Point a useQuery hook at the endpoint to exercise loading, success, and error states. Use the /delay endpoint to see the loading state for a beat, or /status/500 to trigger the error path and test retries:

const { data, isLoading, error } = useQuery({
  queryKey: ["users"],
  queryFn: () =>
    fetch("https://sendwebrequest.com/mock/users").then((r) => r.json()),
});

Try GET /delay/2 (see a loading state) →

Echo your request back

Not sure your client is sending the right headers or body? POST to /echo and it reflects your method, headers, query string, and body back as JSON — the fastest way to confirm what actually went over the wire.

POST https://sendwebrequest.com/echo
Content-Type: application/json

{ "hello": "world" }

Try POST /echo →

Force any status code

Test how your app handles errors by asking for a specific status. /status/404 returns a 404, /status/500 a 500, and so on — handy for exercising error boundaries and retry logic.

Try GET /status/404 →

Is it free? Do I need an API key?

It's free and there's no key, no signup, and no rate-limit sign-up wall. The endpoints are stateless and CORS-open, so you can call them from a browser, a Node script, a test suite, or a tutorial. There are light caps (a max delay of 5 seconds and a capped echo body) to keep it fast for everyone.
