FAQ
What is an Ontology node provider?
An Ontology node provider delivers managed blockchain infrastructure, giving developers instant access to the Ontology 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 an Ontology node?
An Ontology node is software that connects to the Ontology blockchain, validates and relays network data, and provides access to on-chain information. Developers use Ontology nodes to retrieve blockchain data, broadcast transactions, interact with smart contracts, and build wallets, identity solutions, decentralized applications, and other Web3 services. Running a node provides direct access to the network but also requires continuous synchronization and infrastructure management.
Should I run an Ontology node myself?
Running your own Ontology 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 Ontology APIs does NOWNodes support?
NOWNodes provides Ontology RPC API and Archive API through reliable, enterprise-grade infrastructure. These services enable developers to broadcast transactions, retrieve current and historical blockchain data, and interact with the Ontology network without maintaining their own nodes.
How do I start using an Ontology 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 Ontology API.
Can I access Ontology infrastructure for free?
Yes. You can start with our START plan, which provides access to shared Ontology infrastructure with up to 100,000 API requests per month.
