DEVELOPER FIRST

Markets as easy as payments

Create a market, stream quotes, settle outcomes. Escrow, oracle resolution, and regulatory reporting run under the hood — you ship product.

create_market.js
const market = await probable.markets.create({
  question: "Will BTC close above $150k in 2026?",
  closes: "2026-12-31T23:59:59Z",
  oracle: "oracle:consensus",
  liquidity: { seed: 50_000 }
});
// → live in 14ms, quotes streaming
