Hi HN, I m working on PolyBridge. We re building a causal model of global events. You ask a plain-language question about something that might happen in the world and get back a probability, a credible interval, and the reasoning back to source markets.API/docs: https://polybridge.ai/apiWe index 170k+ event contracts across the major prediction-market venues and combine with other data sources in a probabilistic graphical model. It supports 5 query types: current state, forecasts, conditionals (if we observe X, what changes about Y), interventions (if X were forced, what happens to Y), and counterfactuals (what would Y have been if X had gone differently).Example: if there s a direct market on whether the Fed cuts in September but no market on how a spike in oil prices changes those odds. PolyBridge estimates that from the structure connecting rates, inflation, oil, recession risk, and related markets.There s a free API tier with two endpoints: Search and Forecast. Search finds relevant markets and evidence for a text query and Forecast turns a question into a probability with supporting markets and reasoning. We also build Situation Rooms for teams monitoring a topic continuously, like our 2028 Race to the White House room: https://polybridge.ai/situation-rooms/2028-race-to-the-white...I d welcome feedback on the API and examples of questions you d want it to answer. If your team wants a custom Situation Room around a specific topic, get in touch. We re looking for design partners.
