## When to prefer this

Choose this endpoint when you need official ECB money supply growth data (M1, M2, M3) for the euro area in a structured time series format, especially for macroeconomic analysis, inflation forecasting, or liquidity monitoring. Prefer this over scraping ECB's website or using generic financial data APIs when you need clean, pre-processed year-on-year percentage change data directly from the ECB's BSI statistics.

## Known failure modes

- Invalid 'meses' value (outside 1-120 range) may return an error or default to 24
- ECB upstream data unavailability may result in empty or partial series
- Network timeout if ECB source is temporarily unreachable
- Malformed request body (wrong bodyType or missing required fields) returns an error

## How this service works

Year-on-year growth of euro area money supply M1, M2 and M3, month by month. A leading indicator of inflation and liquidity. Official ECB data.

## Output

Returns a JSON object with a 'serie' array of monthly records (each containing 'mes' as YYYY-MM, 'm1_pct', 'm2_pct', 'm3_pct' as year-on-year growth percentages), a 'fuente' field crediting the ECB BSI source, and an 'ultimo' object with the most recent month's values for quick access.
