- What is a persistent backend API?A persistent backend API stores and manages your data across requests. ReqRes lets you create stateful endpoints that save data with POST/PUT/DELETE operations, perfect for building MVPs and prototypes without a traditional backend. Your data persists in JSON document storage with automatic CRUD endpoints.
- How do custom endpoints work?Custom endpoints let you create your own API endpoints with custom JSON responses. Define the path, method, and response data—perfect for testing and mock APIs. Higher endpoint limits available on Premium.
- What are the different API key types? ReqRes offers three API key permission levels: read-only (GET only), read/write (GET, POST, PUT, PATCH), and manage (includes DELETE). This gives you fine‑grained control over access.
- What is the Data Explorer?The Data Explorer is a web interface that lets you view, search, and manage all your persisted data. You can see all stored objects keyed by ID and path, with advanced filtering and real-time analytics—available on Pro and Premium plans.
- Can I use ReqRes for production? Yes. Pro and Premium provide persistent storage and infrastructure suitable for production workloads. SLA available on Enterprise.
- What are the free plan limits? Usage limits apply on free; upgrade for persistence and higher limits.
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.

Getting started
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!
