FAQ

What is a Kusama node provider?

A Kusama node provider delivers managed blockchain infrastructure, giving developers instant access to the Kusama network without the burden of deploying and maintaining their own nodes. Instead of managing synchronization, infrastructure, software updates, and ongoing maintenance, teams can connect to reliable hosted endpoints and start building immediately.

What is a Kusama RPC node?

A Kusama RPC node provides blockchain access through Remote Procedure Call (RPC) endpoints. These endpoints allow developers to broadcast transactions, retrieve block and transaction data, query account and network information, interact with the Kusama blockchain, and monitor on-chain activity. RPC access is the standard way wallets, staking platforms, explorers, and other blockchain applications connect to the Kusama network.

Should I run a Kusama node myself?

Running your own Kusama node is not necessary for most projects. Operating a node requires continuous synchronization, software updates, security monitoring, and dedicated infrastructure. These requirements often make self-hosted nodes costly and time-consuming, particularly as your application grows.

What Kusama APIs does NOWNodes support?

NOWNodes provides Kusama RPC API, Playbook API, Asset Hub API, Asset Hub Playbook API, WebSocket (WSS) API, Asset Hub WSS API, and Archive mode through reliable, enterprise-grade infrastructure. These services enable developers to broadcast transactions, retrieve block and transaction data, access complete historical blockchain records, connect to Kusama's Asset Hub, subscribe to real-time blockchain events via WebSocket, and interact with the network using both standard and Asset Hub-specific endpoints.

How do I start using a Kusama node?

After logging in to NOWNodes and selecting a plan, navigate to the Dashboard in your account and scroll down the page. There you will find the Add a New Key button. Click it to generate your API key, then use it to connect to the Kusama API.

Can I access Kusama infrastructure for free?

Yes. You can start with our START plan, which provides access to shared Kusama infrastructure with up to 100,000 API requests per month.
