Build your backend without code. Create persistent APIs, custom endpoints, and get instant fake data. From prototyping to production, ReqRes has you covered.
ReqRes provides a complete API development platform with three powerful capabilities: persistent backend APIs for data storage, custom endpoints for testing and prototyping, and a free fake data API for instant development resources.
Create stateful APIs that store and manage your data. Perfect for MVPs, prototypes, and production apps.
Build custom API endpoints with your own JSON responses. Ideal for testing, demos, and mock APIs.
Get instant realistic data for testing and prototyping. Ready-to-use endpoints with production-quality JSON.
Create stateful APIs that store and manage your data across requests. Perfect for building MVPs, prototypes, and production applications without traditional backend development.
Build unlimited custom API endpoints with your own JSON responses. Ideal for testing specific scenarios, creating mock APIs, and rapid prototyping.
Enterprise-grade security with multiple API key types, fine-grained permissions, and comprehensive access control for your API development needs.

ReqRes is relied on by developers worldwide for fast, reliable API testing—see our real Cloudflare stats above!
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.
Check out the OpenAPI documentation:
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!

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.
🚀 Your brand, job, or product could be in front of 80+ million developers and 35+ billion API requests every month. ReqRes is where the world's builders, makers, and creators come to test, learn, and launch.
Want to get your message in front of the most engaged, technical audience on the planet? Whether you're hiring, launching, or growing, there's no better place to make an impact.
