Headline fiscal time series: revenue, expenditure, balance and debt ratios over 1990–2029 (actuals plus budget/forecast years).

Use case: track how a federal aggregate evolved over time — e.g. "how did the Bund balance develop since the 2022 rate turnaround?". variable e.g. 'saldo', 'einnahmen', 'ausgaben', 'bruttoschuldenquote'. household: bund|ktn|gdn|staat|sv. model: fs|gfs. Every point flags is_projection. Call fiscal_list_dimensions first to discover valid values; an empty result carries a note with guidance.

Hierarchical federal-budget breakdown for one topic and year.

Use case: see where the money goes — e.g. "which task areas absorbed the spending growth?". topic e.g. 'Ausgaben nach Aufgabengebiet', 'Ausgaben nach Art', 'Einnahmen'. level is the hierarchy depth (1 = total, 2 = first breakdown …); 'contains' filters the path substring for drill-down. An empty result carries a note suggesting a different level or topic.

Federal spending by department / administrative unit since 2007.

Use case: compare personnel, IT or external-services spending across departments — e.g. "IT spending of the Finanzdepartement since 2010?". variable one of: 'Personalausgaben', 'Informatik', 'Beratung und externe Dienstleistungen', 'Anzahl Vollzeitstellen'. An empty result carries a note with guidance.

List the valid dimension values across all datasets (variables, households, models, budget topics, departments).

Use case: call this first to build correct parameters for the other tools — it turns free-text guesses into exact filter values. Loads all three dumps, so it may take a moment on a cold cache.

Report cache freshness and upstream health per dataset.

Use case: check whether the data is fresh, cached or degraded before trusting a figure — the health endpoint of this server. Never returns empty silently; used for graceful degradation.

DEPRECATED — use fiscal_status. Kept as an alias for backward compatibility; will be removed in a future minor release.

Reports cache freshness and upstream health per dataset (SEC-022: every tool now shares the fiscal_ server-identity namespace).
