POST /cpi
unprobed
Gives you official United States inflation numbers from the government's BLS Consumer Price Index. Ask for the newest reading, a specific month in the past, or a whole range of months, and get back clear percentages for overall inflation and 'core' inflation (which ignores food and energy prices), plus a plain-English summary sentence.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
