Predexon is prediction-market infrastructure for builders, traders, and AI agents. One API key gives you everything below.

How it fits together

Read the diagram top-down. Pick the surface you need. Mix freely — most real integrations use REST + WebSocket together, often with MCP for agent-driven flows.

Pick your path

Quant / data trader

You want candlesticks, orderbook history, wallet P&L, smart-money signals, and live WebSocket feeds to build models, dashboards, or backtests.Start with Quant Quickstart →

App builder / platform

You’re building a product that places trades across venues — copy-trading, structured products, prediction-market UX. You want one API, one funding flow, one set of keys.Start with Builder Architecture Guide →

Active trader / fund

You want both: data to find edges, execution to act on them. Cross-venue arbitrage, smart-money following, automated strategies.Start with The combined data + execution flow →

AI agent developer

You’re shipping an agent that reads prediction-market state or places trades. Drop the MCP server into Claude, Cursor, Codex, or your own stack.Start with Agent Cookbook →
