Mock RSS endpoint returning HTTP 201

https://demo-rss-201.supercrontab.com/ answers every request with HTTP 201 Created and a small RSS body. No signup, CORS enabled, nothing logged. Use it to see how your client, retry logic or cron job behaves on a 201 before it happens in production.

Live demo endpoint

https://demo-rss-201.supercrontab.com/

Any method, any path. Returns 201 Created with Content-Type: application/rss+xml. OPTIONS returns 204 with CORS headers.

Call it with curl

curl -i https://demo-rss-201.supercrontab.com/

Call it with fetch

const res = await fetch("https://demo-rss-201.supercrontab.com/");
console.log(res.status); // 201
const body = await res.text();

What HTTP 201 Created means

When you see it
A POST or PUT created a new resource. APIs often return the new object and a Location header pointing at it.
What a client should do
Store the id or Location header from the response. Do not send the same create request again.
Retry?
No

A valid RSS 2.0 feed with one item. Point a feed reader or a cron job at it to test polling.

Questions

Does this endpoint really return HTTP 201 every time?

Yes. Every GET, POST, PUT, PATCH or DELETE to https://demo-rss-201.supercrontab.com/ gets status 201 Created with a small RSS body, whatever the path, query or headers. OPTIONS gets 204 with CORS headers so browsers can preflight.

Should my client retry a 201?

No. Retrying the same request cannot change the outcome. Store the id or Location header from the response. Do not send the same create request again.

Can I get a different format, a delay or a custom body?

The same status is available in JSON, XML, Text, CSV, HTML, YAML, JavaScript. Delays, custom headers, error rates, request logging and your own body need a personal endpoint: sign up and create one at /endpoints in a minute, free.
