How do I create TFS work item using cURL? (cURL is ignoring '$')

curl --request PATCH --header "Content-Type: application/json-patch+json" --data '{"op": "add", "path": "fields/System.Title", "Value": "New Task"}' -u <username>:<token> https://<my_subdomain>$Task

When I use the command above, I get the error below:

{"Message":"No HTTP resource was found that matches the request URI 'https://<subdomain>'."}

(I'm testing this out with VSTS, but plan to use it with TFS)

Text after the '$' in the URL that I am passing to cURL is being ignored.

I tried encoding it as '%24', I tried the url in quotes, and I tried the url without the '$'

Is there a way to use $ in that url?
