A delayed response API for testing loading states

Add a delay to any request to see how your app behaves while it waits: spinners, skeleton screens, retries and timeouts.

?delay=3 waits 3 seconds before responding; the maximum is 10

?delay=random waits between 0.2 and 3 seconds, for more realistic jitter

Works on every classic endpoint, including login and register

curl

curl "https://reqres.in/api/users?delay=3"

JavaScript

console.log(await res.json())

Python

import requests

print(requests.get("https://reqres.in/api/users?delay=3").json())

Ten seconds. Larger values are capped at 10.

Yes. Set your client timeout below the delay, for example a 2 second timeout with ?delay=5.

No. You get the normal response, just later.

Need data that saves?

A free project gives you an API key and collections where records persist, so your demo or tutorial keeps its data.
