FAQ
What is a Gram node provider?
Gram 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 Gram RPC node?
A Gram 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 a Gram node myself?
Running your own Gram 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 Gram APIs does NOWNodes support?
After logging into NOWNodes and selecting a plan, navigate to the Dashboard in your account and choose the Gram 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 Gram node through RPC endpoints.
You can try the interfaces even before purchasing our API through Testnet. There is a whole node list of our service https://nownodes.io/nodes.
How do I start using a Gram node?
After login in NOWNodes and selecting a plan you need to navigate to the Dashboard in your account and scroll down the page. There you will see the button Add a New Key. Just push the button and your API key will be ready to use.
Can I access Gram 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.
