## When to prefer this

Use this endpoint when you need official, authoritative quarterly government debt-to-GDP data for European countries under the Maastricht definition, sourced directly from Eurostat. Prefer it over general economic data APIs when Eurostat provenance, quarterly granularity, and EU/EA aggregate support are required. Especially useful for fiscal comparisons, policy research, or financial analysis requiring the official EU definition of government debt.

## Known failure modes

- Unknown or unsupported country ISO code returns an error or empty result
- Eurostat data lag may mean the very latest quarter is not yet available
- Requesting too many quarters may return only the available history rather than the full requested range
- Malformed body type or missing required fields returns a validation error

## How this service works

General government gross debt (Maastricht) as % of GDP for any European country, quarterly; without a country, a ranking with the latest figure of each. Official Eurostat data.

## Output

Returns a JSON object with the country's ISO code and full name, the most recent quarterly debt-to-GDP figure with its period label, an array of historical quarterly observations (period + debt_pct_gdp), the Eurostat data source attribution, and the last update timestamp. When no country is specified, returns a ranked list of all countries with their latest figures.
