About the PolitPro API

Who is the API For?
The API is designed for media outlets, publishers, think tanks, data providers, and developers who wish to integrate political polling data and election trends into their own products, platforms, or analyses.

How Can I Use the Data?
The data may be used for editorial purposes, within your own products, and for your own clients. However, it is not permitted to build an independent platform whose primary offering consists of political poll data, election trends, or similar competitive services to PolitPro. A separate agreement is required for redistributing the data as part of a data platform or a broader data offering. Please contact us at support@politpro.eu for custom terms.

What Data Does the API Provide?
The API provides current election trends, historical trend developments, and raw data from individual election polls for over 70 parliaments. This data can be filtered by recency or polling institute. We update the data as promptly as possible following the publication of new polls. The current election trend is recalculated with each new poll, while historical trend data points are captured weekly.

Are historical data points subject to revision?
Historical data may be adjusted at any time without prior notice. Corrections may include bug fixes, changes to our weighting methodology, or the retrospective addition of historical data for specific countries. As we continuously expand and refine our datasets, we recommend regularly re-fetching historical data rather than treating it as a static dataset.

How Reliable is the Data?
All data undergoes a rigorous multi-stage quality assurance process, combining advanced algorithms, artificial intelligence, and meticulous manual review. PolitPro is recognized as one of the most reliable sources for European election trends, trusted by international media, leading research institutions, and political organizations alike. All data is provided without guarantee.

Is PolitPro Attribution Required?
Yes, any public display of the data requires clear source attribution, including a link to PolitPro.eu. For example: "Source: PolitPro.eu".

What is the PolitPro Election Trend?
The PolitPro Election Trend aggregates poll results from all relevant institutes into a weighted average. Recent polls are weighted more heavily than older ones, and the historical forecasting accuracy of each institute is also factored in. The result is a statistically robust trend line that smooths out short-term outliers and reveals real political dynamics over time.

What is PolitPro?
PolitPro is Europe's leading platform for election trends and political polling data. International media, political institutions, universities, and research facilities already leverage our data in their daily operations. PolitPro is politically independent, combining public survey data and scientific datasets with proprietary algorithms.
