The filter in the address contains characters that don't have their usual meaning in a URL — typically >, <, a space, or &. If you don't encode them, the request will fail.

A correctly encoded command then looks like this:
curl -u uzivatel:heslo -k -L -f \
"https://server:5434/c/{firma}/faktura-vydana/(datSplat%3Enow()).xml" \
-o ds.xml
💡 You can skip manual encoding — most libraries have a ready-made function for it (in Python urllib.parse.quote, in PHP rawurlencode, in JavaScript encodeURIComponent). A filter typed unencoded into a browser's address bar also gets encoded automatically, so you can just copy it back into the clipboard.
⚠️ Enclose the address in quotation marks. Without them, characters like &, (, and ) will be interpreted by the shell in its own way, and something other than what you wrote will be sent.
