Example prompt: Can you pull up UK house price trend data for England over the last 12 months — I want to see average prices, annual change percentage, and sales volumes month by month?

## When to prefer this

Use this endpoint when you need official UK house price index data broken down by month for a specific UK region, including trend metrics like annual and monthly percentage changes. It is ideal for property market research, investment analysis, or generating regional housing reports. Prefer this over generic property search APIs when you need historical price series data rather than individual property listings or valuations.

## Known failure modes

- Invalid or unrecognised area slug returns an error — must use a valid UK HPI area slug such as 'england' or 'glasgow-city'
- Months value outside 1-120 range may be rejected or clamped
- Most recent months may have null sales volume due to data publication lag
- Payment failure via x402 protocol blocks the request
- Network timeout if upstream HPI data source is slow
