Example prompt: Give me the latest political briefing on the German federal election — what are the current poll simulations showing for party vote shares and possible coalition majorities?

## When to prefer this

Use this endpoint when you need a fast, human-readable political briefing on the current German electoral landscape, including simulated vote shares and coalition scenarios, without needing to query individual election or constituency endpoints. Prefer this over the per-election simulation endpoint when you want a narrative summary rather than raw numeric data, and over the daily date-based briefing endpoint when you want a topic-tagged summary rather than a calendar-anchored briefing.

## Known failure modes

- Unknown or misspelled tag returns no data or an error response
- Briefing content may be in German regardless of caller language preference
- Data is updated every 6 hours so very recent poll movements may not yet be reflected
- uncertainty field may be null for some tags
- notice field may be truncated in the raw JSON

A JSON object containing a headline and multi-sentence briefing text summarising the simulated election landscape (e.g. party vote share medians, coalition arithmetic), the date of the briefing, the timestamp of the last update, data source attribution (dawum.de, ODbL 1.0), and a notice that the output is scenario analysis, not a prediction or voting recommendation.
