=== How To Upload ===
You can upload files to this site via a simple HTTP POST, e.g. using curl:
curl -F "file=@/path/to/your/file.jpg" https://x0.at/?tags=https%3A%2F%2Fworkspace.google.com%2Fblog%2Fsearch%2F%3Fquery%3D%E8%B4%B5%E9%98%B3erp%E7%B3%BB%E7%BB%9F%E4%BA%86%E8%A7%A3%F0%9F%91%80%E7%94%B5%E8%AF%9D%3A18984892410%F0%9F%9A%A2%E8%B4%A2%E5%8A%A1%E6%8A%A5%E8%A1%A8%E6%91%98%E8%A6%81%F0%9F%90%80%E6%8A%BD%E5%A5%96%E8%BD%AF%E4%BB%B6%E5%AE%9A%E5%88%B6%F0%9F%A6%80%E6%9C%89%E4%B8%8D%E8%AE%A4%E8%AF%86%E7%9A%84%E5%AD%97%E5%BA%94%E8%AF%A5%E4%B8%8B%E8%BD%BD%E4%BB%80%E4%B9%88%E8%BD%AF%E4%BB%B6%F0%9F%8F%85%E5%9F%B9%E8%AE%AD%E6%94%AF%E6%8C%81%EF%BC%8C%E8%BD%BB%E6%9D%BE%E4%B8%8A%E6%89%8B%E3%80%82+%E5%85%A8%E9%9D%A2%E7%9A%84%E7%94%A8%E6%88%B7%E5%9F%B9%E8%AE%AD%E4%BD%93%E7%B3%BB%EF%BC%8C%E5%BF%AB%E9%80%9F%E6%8E%8C%E6%8F%A1%E6%93%8D%E4%BD%9C%E6%8A%80%E5%B7%A7%EF%BC%8C%E8%B4%B5%E9%98%B3%E8%B4%A2%E5%8A%A1%E8%BD%AF%E4%BB%B6%EF%BC%8C%E6%96%B0%E8%80%81%E7%94%A8%E6%88%B7%E7%9A%86%E5%AE%9C%E3%80%82%F0%9F%9A%98%E9%87%91%E7%A9%97%E7%A8%8E%E5%8A%A1%E7%B3%BB%E7%BB%9F%3Fkwd%3DYYRJ

Or if you want to pipe to curl *and* have a file extension, add a "filename":
echo "hello" | curl -F "file=@-;filename=.txt" https://x0.at/?tags=https%3A%2F%2Fworkspace.google.com%2Fblog%2Fsearch%2F%3Fquery%3D%E8%B4%B5%E9%98%B3erp%E7%B3%BB%E7%BB%9F%E4%BA%86%E8%A7%A3%F0%9F%91%80%E7%94%B5%E8%AF%9D%3A18984892410%F0%9F%9A%A2%E8%B4%A2%E5%8A%A1%E6%8A%A5%E8%A1%A8%E6%91%98%E8%A6%81%F0%9F%90%80%E6%8A%BD%E5%A5%96%E8%BD%AF%E4%BB%B6%E5%AE%9A%E5%88%B6%F0%9F%A6%80%E6%9C%89%E4%B8%8D%E8%AE%A4%E8%AF%86%E7%9A%84%E5%AD%97%E5%BA%94%E8%AF%A5%E4%B8%8B%E8%BD%BD%E4%BB%80%E4%B9%88%E8%BD%AF%E4%BB%B6%F0%9F%8F%85%E5%9F%B9%E8%AE%AD%E6%94%AF%E6%8C%81%EF%BC%8C%E8%BD%BB%E6%9D%BE%E4%B8%8A%E6%89%8B%E3%80%82+%E5%85%A8%E9%9D%A2%E7%9A%84%E7%94%A8%E6%88%B7%E5%9F%B9%E8%AE%AD%E4%BD%93%E7%B3%BB%EF%BC%8C%E5%BF%AB%E9%80%9F%E6%8E%8C%E6%8F%A1%E6%93%8D%E4%BD%9C%E6%8A%80%E5%B7%A7%EF%BC%8C%E8%B4%B5%E9%98%B3%E8%B4%A2%E5%8A%A1%E8%BD%AF%E4%BB%B6%EF%BC%8C%E6%96%B0%E8%80%81%E7%94%A8%E6%88%B7%E7%9A%86%E5%AE%9C%E3%80%82%F0%9F%9A%98%E9%87%91%E7%A9%97%E7%A8%8E%E5%8A%A1%E7%B3%BB%E7%BB%9F%3Fkwd%3DYYRJ

Or if you want to upload using netcat:
echo "hello" | nc x0.at 9999

Or if you want to upload via SSH (yes, really):
echo "hello" | ssh x0.at

To use a longer file ID (up to 24 characters), add -F id_length=<number>

On Windows, you can use ShareX and import this custom uploader.
On Android, you can use an app called Hupl with this uploader.


Or simply choose a file and click "Upload" below:
(Hint: If you're lucky, your browser may support drag-and-drop onto the file 
selection input.)

 === File Sizes etc. ===
The maximum allowed file size is 222 MiB.

Files are kept for a minimum of 3, and a maximum of 100 Days.

How long a file is kept depends on its size. Larger files are deleted earlier 
than small ones. This relation is non-linear and skewed in favour of small 
files.

The exact formula for determining the maximum age for a file is:

MIN_AGE + (MAX_AGE - MIN_AGE) * (1-(FILE_SIZE/MAX_SIZE))^2
