  • What Are You Curious About?

    We’ve officially launched the Metaculus API, providing access to a rich, quantitative database of aggregate forecasts on 7000+ questions so you can explore, analyze, and build. Find the documentation here.

    A Quick Study

    Running a one-off analysis? You can get started immediately. Building an application that uses the API? First you'll need to authenticate.

    Email api-requests@metaculus.com and tell us about yourself or your organization and what you want to build.

    Note To Early API Adopters from 2020-2023

    We're rapidly improving our forecasting tools and cannot guarantee backward compatibility on all features. If you previously authenticated using cookies, we will support this functionality for now but ask that you please switch to auth tokens by June 1st.

    The more feedback we get, the more useful we can make the API for the forecasting community. We welcome your questions, ideas, and feedback in the comments!
