+
+## Codex
+
+[Codex](https://www.codex.io/) is a blockchain data API that provides real-time and historical DeFi data across 80+ networks via GraphQL, including Celo. With access to over 70 million tokens and 700 million wallets, Codex delivers sub-second data for building token explorers, trading bots, portfolio trackers, and DeFi dashboards.
+
+### GraphQL API
+
+Codex exposes a single GraphQL endpoint with 73 query operations for fetching current and historical data. All requests are sent as HTTPS POST to `https://graph.codex.io/graphql`.
+
+Key query capabilities include:
+
+| **Category** | **Data Available** |
+| --- | --- |
+| **Token Data** | Real-time and historical prices, OHLCV candlestick charts, metadata, and scam filtering |
+| **DEX Trades** | Swap events across decentralized exchanges with pair-level detail |
+| **Liquidity Pools** | Pool reserves, volume, fees, and newly created pairs |
+| **Wallet Activity** | Token balances, transaction history, and holdings across 80+ networks |
+| **Analytics** | Aggregated volume, liquidity, unique wallet metrics, and holder tracking |
+| **Launchpad Monitoring** | Alerts for new token launches and early token discovery |
+
+### Real-Time Subscriptions
+
+Codex supports 25 real-time data streams via WebSocket (`wss://graph.codex.io/graphql`), enabling live updates for:
+
+- Token price changes and trade events
+- New and updated DEX pairs
+- Wallet activity and balance changes
+- Launchpad and new token events
+
+### Webhooks
+
+Webhooks provide push-based notifications for on-chain events, delivering data to your server as events occur without requiring persistent WebSocket connections.
+
+### SDK
+
+Codex provides a TypeScript/JavaScript SDK that acts as a thin wrapper around the GraphQL API with predefined queries, mutations, and built-in subscription connection handling.
+
+```bash
+npm install @codex-data/sdk
+```
+
+Alternatively, you can write custom GraphQL queries directly against the API for more flexibility.
+
+### Getting Started
+
+#### 1. Create an account
+
+Sign up at [dashboard.codex.io](https://dashboard.codex.io/signup) to create your Codex account.
+
+#### 2. Get your API key
+
+Copy your API key from the API Keys page in the dashboard.
+
+#### 3. Make your first request
+
+All requests require an `Authorization` header with your API key.
+
+```bash
+curl -X POST https://graph.codex.io/graphql \
+  -H "Content-Type: application/json" \
+  -H "Authorization: YOUR_API_KEY" \
+  -d '{"query": "{ getNetworks { name id } }"}'
+```
+
+#### 4. Explore the API
+
+Use the [GraphQL Explorer](https://docs.codex.io/explore) to interactively build and test queries.
