FAQ
What is a Polkadot node provider?
A Polkadot node provider delivers managed blockchain infrastructure, giving developers instant access to the Polkadot 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 Polkadot node?
A Polkadot node is software that connects to the Polkadot blockchain, validates and relays network data, and provides access to on-chain information. Developers use Polkadot nodes to retrieve blockchain data, broadcast transactions, interact with parachains, and build wallets, staking platforms, explorers, and other Web3 applications. Running a node ensures direct access to the network but also requires ongoing maintenance and infrastructure management.
Should I run a Polkadot node myself?
Running your own Polkadot 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 Polkadot APIs does NOWNodes support?
NOWNodes provides Polkadot RPC API, Playbook API, Asset Hub API, Asset Hub Playbook API, WebSocket (WSS) API, and Asset Hub WebSocket (Asset Hub WSS) API through reliable, enterprise-grade infrastructure. These services enable developers to broadcast transactions, retrieve blockchain data, access the Polkadot Asset Hub, automate Asset Hub workflows, and subscribe to real-time blockchain events without maintaining their own Polkadot nodes.
How do I start using a Polkadot 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 Polkadot API.
Can I access Polkadot infrastructure for free?
Yes. You can start with our START plan, which provides access to shared Polkadot infrastructure with up to 100,000 API requests per month.
