How this service works
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.
Output
A JSON response containing official US CPI inflation data — either the most recent month's figure, a specific month's figure, or a series of monthly figures across a requested date range, along with API version metadata.
Example use cases
Example prompt
“Can you pull up the official US CPI inflation figures for every month from January 2022 through December 2024?”
