+## Zerion API
+
+[Zerion API](https://zerion.io/api/base) is an enterprise-grade wallet data API that provides token balances, DeFi positions, NFTs, and transaction history on Base, other major EVM chains, and Solana. It covers over 8,000 DeFi protocols and delivers sub-second responses through a unified schema, so teams don't need to build or maintain their own indexers.
+
+Zerion API supports:
+
+- **Token balances and prices:** Real-time interpreted portfolio data with built-in conversions to USD and major currencies.
+- **DeFi positions:** LP, staking, lending, and other protocol positions decoded and normalized.
+- **Transaction history:** Human-readable, enriched transaction feeds ready for UIs or exports.
+- **NFT holdings:** Full NFT portfolio data including metadata and floor prices.
+
+To get started, visit the [developer documentation](https://developers.zerion.io/) or create free API keys on the [Zerion API for Base](https://zerion.io/api/base) page.
