How this service works
US inflation (CPI-U): year-on-year headline, core (ex food and energy), energy and food rates, month by month. US Bureau of Labor Statistics, public domain.
Output
Returns a JSON object with four time series (ipc_general, ipc_subyacente, ipc_energia, ipc_alimentos) each containing monthly entries with the CPI index value and year-on-year percentage change, plus a 'ultimo' object with the most recent available data point for each category. Source attribution to the U.S. Bureau of Labor Statistics (CPI-U, non-seasonally adjusted) is included.
Example use cases
Monthly inflation briefing for analyst
“Give me the US CPI breakdown for the last 12 months — I need headline, core, energy, and food inflation rates year-over-year so I can put together a macro briefing.”
Energy price inflation trend tracking
“What's the year-on-year energy CPI trend in the US over the past 6 months? I want to see how energy inflation has been moving month by month.”
Core vs headline inflation comparison
“Pull the last 24 months of US CPI data so I can compare core inflation against the headline number and see how much food and energy are distorting the overall figure.”
Technical details
Endpoint
POSThttps://api.vextorium.com/ipc-eeuu-pago?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, ready-to-use US CPI inflation data broken out by headline, core, energy, and food sub-indices in a single call, without having to parse raw BLS files or build your own aggregation. It is especially useful for agents that need to compare sub-components (e.g. energy vs core) or build month-by-month trend charts. Prefer alternatives if you need international inflation data, seasonally adjusted series, or non-CPI price indices (e.g. PCE, PPI).
Side effects
- Invalid 'meses' value outside 1-24 range may return an error or default behavior
- BLS data lag may mean the most recent month is not yet available
- Network or payment failure returns no data
- Malformed request body returns a validation error
