-## What are Chain APIs?
+## What are the Chain APIs?
 
-Alchemy's Chain APIs provide comprehensive access to blockchain data and functionality across all supported networks. These APIs enable you to interact with blockchains through standardized JSON-RPC methods, allowing you to read blockchain state, write transactions, and build powerful decentralized applications.
+Alchemy's Chain APIs are our implementation of the standard JSON-RPC interface (as defined by Ethereum) and compatible equivalents for non-EVM chains (e.g., Solana, Bitcoin). They provide direct, low-level access to blockchain data and functionality across all supported networks: read blockchain state, submit transactions, and build powerful decentralized applications.
 
-## Key capabilities
+> Looking for higher-level building blocks?
+> For indexed, enriched queries use the **[Data APIs](/docs/reference/data-overview)**.
+> For account-abstraction and smart-wallet flows use the **[Wallet APIs](/docs/wallets)**.
+
+## Companion APIs
+
+Use these alongside the standard JSON-RPC methods for streaming, performance, and deeper inspection. Chain coverage varies: check each page for supported networks.

+## Key capabilities
 
 * **Read Operations**: Query account balances, smart contract state, transaction history, block data, and more
 * **Write Operations**: Submit transactions to the network and track their status
 * **Event Monitoring**: Subscribe to real-time blockchain events via WebSockets
 * **Gas Management**: Estimate transaction costs and optimize gas usage
 * **Network Information**: Access chain-specific data like network version, block numbers, and protocol details
 
+Most chains use the **same EVM JSON-RPC methods** (e.g., `eth_call`, `eth_getLogs`, `eth_sendRawTransaction`); non-EVM chains provide compatible JSON-RPC or equivalent endpoints, plus **chain-specific methods** where the protocol differs. Each chain's section in the sidebar covers its full method list, endpoint URLs, and chain-specific behavior and limits.
