INE Spain (Tempus3 JSON API)

Instituto Nacional de Estadística (INE) · CPI and HICP are monthly, published mid-month for the prior month; a flash estimate (T3_TipoDato 'Preview', observed live 2026-07-31 for July) lands at month-end roughly two weeks ahead of the final and is served as the current vintage until the final revises it. In January 2026 INE rebased the whole consumer-price universe to Base 2025 with the ECOICOP ver.2 classification, STOPPING the Base-2021 series at 2025-12 under their old codes — the curated CODs are the living Base-2025 ones.
