+## Codex
+
+The [Codex Data API](https://www.codex.io) is a real-time blockchain data API for building trading apps, token screeners, and portfolio trackers. Codex indexes token prices, OHLCV charts, DEX pairs and trades, liquidity, holders, and wallet balances across [80+ networks](https://docs.codex.io/networks), including Base. Codex also indexes Base's native [B20 tokens](/base-chain/specs/upgrades/beryl/b20), identifying them as B20 and tracking their multiplier, supply cap, and paused status.
+
+Data is served through a single GraphQL API, with WebSocket subscriptions for streaming live prices, charts, and trades, and webhooks for event notifications. An official [TypeScript SDK](https://docs.codex.io/sdk) is available, and any [GraphQL](https://docs.codex.io/learn-graphql) client can query the API directly.
+
+To get started, [sign up](https://dashboard.codex.io/signup) to create an API key, then visit the [documentation](https://docs.codex.io) or follow the [getting started guide](https://docs.codex.io/get-started).
