Send json to webservice and return status

I'm taking a course from Caelum 36 but I packed up at one point I need to do this:

curl -i -H "Content-type: application/json" -X POST -d '{"valor":"39.9","titular":"Fulano"}' http://localhost:8080/fj36-webservi
ce/pagamento

Only in the terminal is this turning me

HTTP/1.1 400 Bad Request

X-Powered-By: Undertow/1
Server: WildFly/8

What do I do to work? I can not handle that mistake. You are on page 98 (who has the booklet)

Error that appears in terminal:

com.fasterxml.jackson.core.JsonParseException: Unexpected character (''' (code 39)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')
