httpstat.us

This is a super simple service for generating different HTTP codes.

It's useful for testing how your own scripts deal with varying responses.

Just add the status code you want to the URL, like this: httpstat.us/200

We'll return a response like this:

HTTP/1.1 {status code} {status description} Content-Type: text/plain or application/json Content-Length: {something} {any custom response headers} {status code} {status description} {list of any custom response headers we added}

To get a JSON response back, you need to ensure that the Accept header contains 'application/json'. Then we'll JSON encode the response and send the Content-Type header accordingly.

To get a random response back, use the random/{range} endpoint, for example httpstat.us/random/200,201,500-504. You can duplicate ranges in order to increase their probability.

If you want a delay on the response add a query string or provide a header of X-HttpStatus-Sleep for the sleep duration (the time in ms, max 5 minutes*), like this: httpstat.us/200?sleep=5000
*When using the hosted instance the timeout is actually 230 seconds, which is the max timeout allowed by an Azure App Service (see this thread post). If you host it yourself expect the limits to be different.

If you want to return additional headers to the client, you can send them in the request with the X-HttpStatus-Response- prefix. A header of X-HttpStatus-Response-Foo: Bar will append the Foo: Bar header in the response.

If you need to enable CORS, all endpoints have been configured to allow all origins, headers, and HTTP methods.

If you send any other three digit number that's not in that list, we'll return it too. Or, send us a pull request to add full support for a new code.

Enjoy!
