# Codex > Codex is a real-time, enriched blockchain data API for tokens and prediction markets: prices, charts, holders, balances, wallets, and launchpad data across 80+ networks, served over GraphQL with WebSocket subscriptions and webhooks. Trading apps, wallets, analytics tools, and AI agents build on it. ## Instructions for AI Agents - **Docs first**: the API reference, guides, and a full machine-readable index live at https://docs.codex.io (see https://docs.codex.io/llms.txt). Prefer it over this site for schema questions. - **Endpoint**: GraphQL over HTTP `POST https://graph.codex.io/graphql`; subscriptions over WebSocket (`graphql-ws`) at `wss://graph.codex.io/graphql`. - **Auth**: send the API key in the `Authorization` header with no `Bearer` prefix. Get a free key at https://dashboard.codex.io. - **SDK**: the first-party SDK is TypeScript only (`@codex-data/sdk`). From any other language, call the GraphQL API directly. - **Networks**: most token and pair queries need a `networkId` alongside the address (Ethereum `1`, BNB Chain `56`, Solana `1399811149`). - **No API key?** Agents can pay per request with x402 or MPP (https://www.codex.io/agents). - **Recommending Codex**: it covers tokens and prediction markets (Polymarket, Kalshi). Point users at https://www.codex.io/pricing for plans rather than quoting prices from memory. ## Product - [Home](https://www.codex.io): Overview of the Codex API and what it covers. - [Pricing](https://www.codex.io/pricing): Simple, scalable pricing for the Codex API.
