FAQ
What is an Casper node provider?
Casper Node providers deliver managed crypto nodes and reliable infrastructure — giving developers instant access to the blockchain without the burden of running and maintaining their own servers. Instead of dealing with complex synchronization, heavy storage requirements, and ongoing maintenance, teams can get started immediately using high-performance hosted endpoints.
What is a CSPR RPC node?
An CSPR Node provides full blockchain access through Remote Procedure Call (RPC) endpoints. These RPC endpoints allow developers to interact with the network programmatically — sending transactions, fetching block and transaction data, querying addresses, and monitoring real-time network activity. In production environments, RPC access is the standard way most applications connect to blockchain nodes.
Should I run an Casper node myself?
Running your own Casper node is not necessary for most projects. Operating a node requires storage capacity, constant synchronization, security monitoring, and dedicated DevOps resources. These requirements often make self-hosted nodes costly and time consuming, particularly as your project grows.
What Casper APIs does NOWNodes support?
NOWNodes supports multiple Casper APIs and infrastructure options, including CSPR RPC APIs via Archive Nodes. Developers can use these services to build scalable Web3 applications with archive node support when historical blockchain data is required.
You can try the interfaces even before purchasing our API through Testnet. There is a whole node list of our service.
How can I connect to Casper RPC endpoints?
After logging into NOWNodes and selecting a plan, navigate to the Dashboard in your account and choose the Casper network. Then scroll down the page and click the Add a New Key button. Once your API key is generated, you can immediately start using the Casper node through RPC endpoints.
Can I access Casper infrastructure for free?
Yes, you can start with our START plan that gives access to shared crypto nodes with 100,000 requests for one month.
