How this service works
Latest federal polls (Sonntagsfrage), party names normalised. Use when asked about the newest federal polls by institute. Source-attributed. Refused (503, not charged) if data is older than 13 hours.
Output
A JSON object with an array of recent poll records, each containing the poll ID, polling institute, publication date, parliament name, sample size, fieldwork start/end dates, commissioner, polling method, and a results object mapping party names (AfD, SPD, CDU/CSU, Grüne, FDP, BSW, Linke, Sonstige) to their vote share percentages. Also includes data source attribution (dawum.de, ODbL 1.0), an uncertainty notice (sampling error ~2–3 points per party), a last-updated timestamp, and a documentation URL.
Example use cases
Live coalition math after new poll
“A new INSA poll just dropped — can you pull the latest German Bundestag polls and tell me which two- or three-party coalitions would have an arithmetic majority based on the current numbers?”
Party trend monitoring for political analyst
“I'm tracking the AfD and SPD numbers week over week — fetch the last 10 German Bundestag polls so I can compare their vote share trends across institutes.”
Election briefing for a news summary
“Give me a quick briefing on where all the major German parties stand right now — pull the 3 most recent Bundestag polls with the institute name, sample size, and fieldwork dates.”
Technical details
Endpoint
GEThttps://api.polls.karbach.digital/v1/polls/latest?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need the latest raw poll figures for German federal or state elections, including party-level vote shares, institute details, and fieldwork metadata — especially when you want a batch of the most recent surveys rather than a single election's aggregated scenario model. Prefer over sibling endpoints when the user needs current polling numbers rather than simulation results, constituency breakdowns, or historical official results.
Side effects
- No recent polls available if data source (dawum.de) has not published new polls recently
- Limit parameter out of range (must be 1–50) returns validation error
- Service may return stale data if the 6-hour refresh cycle is currently running
- Paid endpoint — missing or invalid x402 payment header results in 402 Payment Required
- Network timeout if upstream data source is unavailable
