# @polkadot/api

This library provides a clean wrapper around all the methods exposed by a Polkadot/Substrate network client and defines all the types exposed by a node. For complete documentation around the classes, interfaces and their use, visit the [documentation portal](https://polkadot.js.org/docs/api/).

If you are an existing user, please be sure to track the [CHANGELOG](CHANGELOG.md) and [UPGRADING](UPGRADING.md) guides when changing versions.
