Futuur Prediction Markets API — oanor API marketplace

Futuur Prediction Markets API

Live prices from Futuur, a global prediction market where users trade on the outcome of real-world events across crypto, politics, sports, science and economics — in both real money (USDC) and play money — served from the public Futuur API, no key, nothing stored. Each market asks a question (for example "Which price will Bitcoin hit in 2026?") and holds two or more outcomes whose price, between 0 and 1, is the market-implied probability of that outcome — an outcome trading at 0.46 means the market prices a 46% chance. The markets endpoint lists markets, filterable by category and search term, each with its outcomes and prices. The market endpoint returns a single market with every outcome's real-money and play-money price (and implied probability) plus its category, status and close date. The categories endpoint lists the topic categories from Bitcoin to elections to sports. Read what a worldwide crowd is pricing in for the future, as live JSON. This is the global prediction-market / event-probability cut — distinct from the US-politics-only (PredictIt) and crypto-only (Polymarket) prediction markets and the price and FX APIs in the catalogue.

PredictIt Political Markets API — oanor API marketplace

PredictIt Political Markets API

Live prices from PredictIt, the real-money political prediction market where traders buy and sell shares in the outcome of US elections, economic events and policy questions — served from PredictIt's public market-data feed, no key, nothing stored. Each market asks a question (for example "Which party will control the House?" or "Who will win the 2028 presidential election?") and holds one or more yes/no contracts whose price, between 0 and 1 US dollar, is the market-implied probability of that outcome — a contract trading at 0.27 means the market prices a 27% chance. The markets endpoint lists every open market with its question and contract count. The market endpoint returns a single market with every contract — last trade price, best buy and sell yes/no quotes, last close — and the implied probability. The search endpoint finds markets by keyword (president, Senate, Fed, shutdown). Read what bettors really think will happen, as live JSON. This is the political prediction-market / event-odds cut — distinct from the crypto prediction markets (Polymarket) and the play-money markets in the catalogue.

Search markets and get each one's question, current probability, mana volume, unique-bettor count, liquidity and creator. Read one market in full, with its description and close time. See the top holders of a market — who is forecasting which way and how much mana they have invested. Read a forecaster's profile: their mana balance, all-time profit and how many markets they have created. Live, no key, nothing stored. Distinct from real-money prediction-market and sports-odds APIs — this is Manifold's community markets, their crowd probabilities and their forecasters.
