+The Stacks 2.0 Blockchain API is a centrally-hosted API that is accessible via the internet and enables interactions with the publicly-viewable state of the Stacks 2.0 blockchain, including transaction, account, and smart contract data.
 
 The [Node RPC API](/references/stacks-rpc-api) is locally-hosted and runs on Stacks 2.0 Blockchain nodes, providing similar functionality but in a way that is scoped to that specific node, giving access to raw transaction data as the node sees it.

 ## Introduction
 
-The Stacks 2.0 Blockchain API was built to maintain pageable materialized views of the Stacks 2.0 Blockchain. It is a server that exposes a RESTful JSON API, hosted by PBC. It introduces aidditonal functionality (e.g. get all transactions), as well as proxies calls directly to Stacks Node. [You can find the OpenAPI specification and documentation here](https://blockstack.github.io/stacks-blockchain-api/).

 ~> Note: Using this API requires you to trust the server, but provides a faster onboarding experience. It also addresses performance issues for which querying a node itself would be too slow or difficult
 
+## Client library
+
+A generated JS Client is available for consumption of this API. The client library enables typesafe REST and WebSocket communication. [Please review the client documentation for more details](https://blockstack.github.io/stacks-blockchain-api/client/index.html).
