## When to prefer this

Choose this endpoint when you need authoritative UK CPI inflation data sourced directly from the Bank of England and ONS, especially when you need a configurable historical time series (up to 10 years). Prefer it over generic finance APIs when UK-specific, official government inflation data is required, or when building dashboards, economic reports, or cost-of-living analyses focused on the UK.

## Known failure modes

- Invalid months value (outside 1-120 range) returns a validation error
- Payment failure or insufficient USDC balance returns a 402 error
- Data source unavailable (Bank of England / ONS outage) may return a 503 or empty dataset
