      What this check looks for
    Description, as the server wrote it
    Use this when the user asks a us inflation calculator question, for example what is $100 worth today, the value of money over time, or a dollar inflation calculator, buying power calculator or consumer price index calculator request for US dollars. It converts one US dollar amount between two periods with the published CPI-U index and returns the adjusted amount, both index values, the cumulative inflation, the average annual rate, and the buying-power change. It works for published periods from 1913-01 to the latest bundled month, year or YYYY-MM inputs, and amounts greater than zero up to one trillion dollars including fractional cents; only the output is rounded to cents. Do not use for other countries, for regional or core CPI, for forecasts, or for financial advice.

    Description, as the server wrote it
    Use this when the user wants a consumer price index calculator, inflation rate calculator or cpi calculator across many years: a year-by-year table of the annual average CPI-U and the yearly inflation rate, with a CSV download. It uses the bundled published CPI-U series for 1913 through the latest full year, up to 120 years per call. Do not use for a single amount conversion (use adjust_for_inflation), for other countries, for monthly percent changes, or for forecasts.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
