Advanced API tools

Advanced APIs for Ethereum and all supported networks — from real-time WebSocket streams to deep historical and indexed data.

Real-time WebSocket access on supported networks.
Subscribe to new blocks, transactions, and events without polling.

Access full blockchain history on supported networks.
Query historical states and logs beyond pruned node limits.

Advanced tracing and debugging methods on supported networks.
Inspect transactions, internal calls, and execution paths.

High-level indexed blockchain data via a unified API. Access addresses, transactions, balances, and blocks without raw RPC calls.

Flexible Ethereum API infrastructure

Clear pricing and shared infrastructure with no hidden limits or unexpected restrictions for Ethereum.

No RPS limits

There are no predefined RPS limits on paid plans. Throughput scales dynamically based on cluster capacity, without artificial throttling.

Flexible pricing

Plans for different budgets — from shared access to dedicated nodes. Combine tariffs to optimize costs without sacrificing performance.

Geo-balanced infrastructure

Requests are served through geo-distributed, load-balanced node clusters. Automatic failover maintains availability if nodes go offline.

120+ Blockchains

One RPC provider — 120+ blockchains. We regularly add new chains, including by request from our users. Check out our crypto node list.

99,95% Uptime

Reliable performance under any load — with smart load balancing. We ensure stable performance and deliver on our SLA.

24/7 Suport

Our support team consists of experienced technical experts. With a clear SLA, we guarantee help, with first responses in under 3 minutes.

FAQ

What is a Ethereum node provider?

Ethereum 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 Ethereum RPC node?

A Ethereum 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.

Do I need to run my own Ethereum node?

Running your own Ethereum 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 Ethereum APIs does NOWNodes support?

NOWNodes supports multiple Ethereum APIs and infrastructure options, including Ethereum RPC APIs, BlockBook APIs, Archive APIs, WSS (WebSocket) APIs, and BlockBook WSS APIs across both Mainnet and Testnet environments. Developers can use these services to access blockchain data, retrieve wallet and transaction information, stream real-time updates, debug applications, trace transactions, and 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 https://nownodes.io/nodes.

How do I start using a Ethereum node?

After logging into NOWNodes and selecting a plan, navigate to the Dashboard in your account and choose the Ethereum 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 Ethereum node through RPC endpoints.

Can I get a free Ethereum node?

Yes, you can start with our START plan that gives access to shared crypto nodes with 100,000 requests for one month.
