It’s all in the details

  • Hosted on Cloudflare

    Which means 99.9% Uptime SLA.
    All you need is the base URL, and you're away:

    https://reqres.in/api/

    The API is CORS enabled, so you can make requests right from the browser, no matter what domain, or even from somewhere like CodeSandbox or StackBlitz.

  • Language agnostic

    A generic API that conforms to REST principles and accepts a content type of

    application/json

    Any endpoint that contains "<resource>" can be substituted with anything you supply, ie. "products", "accounts", etc..the API will just respond with various Pantone colours.

Modern JavaScript (Fetch)

If you, for example, want to create a fake user:

fetch("https://reqres.in/api/users", {
    method: "POST",
    headers: {
        "Content-Type": "application/json",
        "Authorization": "Bearer YOUR_API_KEY"
    },
    body: JSON.stringify({
        name: "paul rudd",
        movies: ["I Love You Man", "Role Models"]
    })
})
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.error("Error:", error));

For which the response to this request will be...

{
    "name":"paul rudd",
    "movies":[
        "I Love You Man",
        "Role Models"
    ],
    "id":"243",
    "createdAt":"2025-01-15T12:09:05.255Z"
}

You can see that the API has sent us back whatever user details we sent it, plus an id & createdAt key for our use.

Async/Await JavaScript

If you've already got your own application entities, ie. "products", you can send them in the endpoint URL, like so: 

async function getProduct() {
    try {
        const response = await fetch("https://reqres.in/api/products/3", {
            headers: {
                "Authorization": "Bearer YOUR_API_KEY"
            }
        });
        const data = await response.json();
        console.log(data);
    } catch (error) {
        console.error("Error:", error);
    }
}

getProduct();

It would be impossible for Reqres to know your application data, so the API will respond from a sample set of Pantone colour data 

{
    "data":{
        "id":3,
        "name":"true red",
        "year":2002,
        "pantone_value":"19-1664"
    }
}

It's entirely possible to get sample data into your interface in seconds!

Still don't really get it...

  • Reqres is a real API

    Reqres simulates real application scenarios. If you want to test a user authentication system, Reqres will respond to a successful login/register request with a token for you to identify a sample user, or with a 403 forbidden response to an unsuccessful login/registration attempt.

    A common front-end scenario that's easily forgotten is loading states, which can be easily simulated through Reqres by appending
    ?delay=<a number of seconds> to any endpoint URL, which will delay the API response time. Perfect for testing loading spinners and skeleton screens!

  • Technical demos and tutorials

    If you're trying to demonstrate a front-end (JavaScript-based) concept, you don't really want the hassle of setting up an API, or even a server (especially during a live workshop or demo).

    You can just write your HTML, CSS & JavaScript as usual and send Reqres AJAX requests, which will respond with the expected response codes and output.

  • Rapid prototyping of interfaces

    When prototyping a new interface, you just want an API there, with minimal setup effort involved. While you could set up your own backend with tools like Next.js API routes or Vercel Functions, that requires deployment and configuration.

    Reqres is just a URL. Sending it an HTTP request is step 1...there is no step 2. Perfect for rapid prototyping, demos, and testing.

Peace of mind

It might seem pretty weird to be sending your data to a 3rd party API, but I can assure you, Reqres does not store any of your data at all. Once you send it to us, we just send it straight back...and then it's gone!
