Use this endpoint when you need official Spanish residential property price index data from INE, broken down by autonomous community or nationally, with quarterly and multi-year trend percentages. Prefer this over general real estate listing APIs when you need macroeconomic benchmark data rather than individual property prices.
Side effects

- Data may lag by one quarter if INE has not yet published the latest release
- National-only data returned if region parameter is omitted
- Service downtime on Railway hosting may cause 5xx errors
