## Files upload
For files upload, there are [Files](#tag/files) endpoints.
The file is uploaded to a temporary storage which is not accessible
publicly. The file is kept there for 7 days and then deleted.
After you upload a file, you may copy it to some API entities in their
endpoints - you specify filename returned in response of upload job.
Please note that currently only images (png, jpg, gif) are allowed filetypes
for file upload.
