How this service works

Output

Results are filterable by date range or exact observation date, with up to 100 observations by default.

Technical details
Endpoint
GEThttps://marketdata.use.x402atlas.com/inflationWhen to prefer
Choose this endpoint when you need authoritative US inflation macro data (CPI and PCE) directly sourced from Federal Reserve time series, especially when you need both headline and core variants side-by-side with year-over-year rates. Prefer over generic data providers when you need structured, filterable historical inflation data with consistent Federal Reserve sourcing and per-call micro-payment access without a subscription.
Side effects
- Invalid date format (not YYYY-MM-DD) returns a 400 error
- Date range with no available observations returns empty result set
- limit=0 or negative limit may return error or empty set
- Future dates return no data since Fed data is historical only
- Payment failure (insufficient USDC) returns 402 before data is served
