About
Codex is an API for enriched blockchain and prediction market data. For tokens, it covers real-time pricing, charts, holders, balances, and aggregated analytics for 80M+ tokens and 700M+ wallets across 80+ networks (EVM chains and Solana), with sub-second freshness, historical USD pricing, and WebSocket and webhook subscriptions.
Codex also provides prediction market data across Polymarket and Kalshi through a single schema. This includes events, markets, traders, holdings, live order books, and trade feeds, along with time-windowed stats and ranking signals (volume, liquidity, open interest, trade count, and unique traders) at 5m through 1w windows that the venue APIs do not expose natively.
Codex is a GraphQL API that most teams query directly, with an optional TypeScript SDK. There is also an MCP server for reading the documentation. Codex offers a free tier (10,000 requests/month), usage-based Growth pricing, and Enterprise plans. Developers use it to build trading platforms.
