GetBlock is a service that provides instant API connection to full nodes from many leading blockchain platforms. The mission of GetBlock is to ensure cost-effective tools and infrastructure that helps enterprises and individual developers to build high-quality decentralized applications (dApps) faster.

GetBlock currently supports mainnets and testnets of over 40 blockchain protocols. All the relevant information on the supported blockchain nodes can be found on Shared Nodes and Dedicated Nodes pages. If you can’t find the node you need, please, contact us and we will do our best to add the requested node to our platform.

Our main servers are currently located in Europe (Germany, Finland, and the Netherlands). We serve our clients worldwide and see great latency in all regions. If you need any particular server location, please, contact us and we will negotiate all possible solutions.

The process of running and maintaining blockchain nodes has a lot of technical issues, it's time-consuming, and requires heavy expenses, etc. GetBlock solves many of these problems by providing easy-to-use, high-performance, and reliable service which replaces the need to run your own node.

We facilitate the lives of individual developers, startups and enterprises by providing them with the all-in-one tool for fast and easy integration of decentralized networks to their business projects:

• We provide access to an unmatched range of networks and smart contracts platforms.
• You don’t need to attach your credit/debit card to register at GetBlock. You can simply login and start using the service.
• Our pricing model is quite convenient because users do not overpay for unused requests. The unused requests from any purchased package will be carried over to the next month in your account, as there is no time limit for use.
• We guarantee a fully responsive customer care system. Helpful consulting and technical support is provided by our highly-skilled team of experts 24/7.

Yes, we offer a general Service Level Agreement (SLA) to our customers. If your project requires a certain level of performance, we can negotiate and conclude an individual SLA according to your needs.

Blockchain nodes store a complete copy of the distributed ledger and are responsible for the reliability of the stored data. Nodes participate in consensus, share information about transactions and the number of funds, confirm transactions and store copies of confirmations, participate in the building of new blocks in the chain, for which they receive a reward. Nodes are used by developers for building blockchain-based applications.

A full node stores all the data in the blockchain, including block headers and data records. It participates in block validation and verifies all blocks and states. An archive node stores everything kept in the full node and builds an archive of historical states.

A dedicated node is more stable since it’s built for a particular client and receives a workload only from him. It also has a higher speed than a shared node since the workload is less. The number of requests that can be sent to the dedicated node is unlimited. As for the shared nodes, the number of requests depends on the chosen package.

Rate limits, the number of API calls an app or user can make within a given time period, are set to a maximum of 30 requests/second. The limits can be exceeded due to overall usage (autoscaling).

There is no rate limiting.

The speed of a dedicated node depends on many factors that affect performance: Internet connection, location of a user and the dedicated node itself, requests (methods) that the user sends, a blockchain and server power. On average, the speed of a shared node is ~ 0.01 sec, and of a dedicated node is ~ 0.004 sec.

GetBlock provides several solutions to increase the node speed. To learn more, please, contact our team.

Yes, we provide access to archive data on dedicated nodes for most of the supported blockchains. Please, write us back to get the actual information.

It’s quite easy to get started with GetBlock – simply register an account and get your API key for interaction with the required blockchain.
Please, check out the How to set up an account and Authentication with API Key tutorials that will help you get set-up with GetBlock and start using our node service.

To get connected to a blockchain node, you need to send a request to it. You interact with a node by sending requests to and receiving responses from it via an API. Check out the Authentication with API Key guide to learn more about sending requests to blockchain nodes with GetBlock.
Since we process two types of requests – JSON RPC and WebSockets – they are counted differently. One JSON-RPC request is equal to one requested method from a node, for example, if a user requests three methods in one request in the form of a batch, then our system counts each method and he will spend three requests. As for WebSockets, each response is considered as one request.

The method call is essentially what function a user asks a certain node to execute. Each node has its own set of methods for interaction with the blockchain network which can be found here.

Some requests usage goes beyond the GetBlock.io’s security policy. Particularly, wallet methods (e.g. create a wallet) and those that require private keys to be included (e.g. signing contracts) are strictly prohibited since requiring personal data. The unavailable methods differ depending on a blockchain, for more information please check the Available Nodes Methods section in the GetBlock Documentation.

GetBlock Dashboard is the user's personal page that allows working with API keys, tracking request volume, monitoring statistics, making purchases, and using docs and information about features that are stored. You can set a timespan, check methods for a particular blockchain and monitor valuable insights to understand how your dApp is being used.

The statistics for dedicated nodes are not available at the moment. This feature is under development and will be available soon.

We have an internal monitoring system that helps us to track node performance. If a user needs a custom monitoring system, we can develop and integrate it by request.

The rate limit on shared nodes is 30 requests/second. A user will receive ‘Response code: 429 Too Many Requests’ for each request sent above this limit. Such requests will not be charged off and displayed on the dashboard.

Yes, you can use one API key and connect to all nodes you need at the same time.

Currently, we accept payments in ERC-20 tokens (Bitcoin, Ethereum, Bitcoin Cash, Litecoin, USD Coin, Dogecoin, and Dai. Also, the clients can use the pay with Coinbase option on the order form.
If you want to pay in BEP-20 tokens, please, send us a message. We accept USDC, USDT, BNB, TOT, BUSD.

Payments via bank transfers are available for unlimited shared package and the dedicated node users. Individual agreement is necessary.
For other packages we accept only crypto payments. If you want to make withdrawals from fiat to crypto, we can offer to use the platform of our partners. But the minimum payment amount, in this case, will be $50. To learn more, please, contact our customer support managers.

As for the shared nodes, GetBlock provides several fee-based packages – Newbie, Light, Base, Popular, Team, Unlimited – to fit a wide range of budgets and company sizes. Also, we offer a Free package that helps our clients to test their developer’s skills and the service itself.
To get the pricing information for the dedicated nodes, please, contact our customer support.

They differ only by the number of requests to be used. In other words, you can test out the node without buying one of the request packages. The result will be exactly the same as if you bought the package.

A ‘Free' plan offers 40,000 requests that can be used for all our supported shared nodes. These requests are automatically charged to the user’s account once per day. The unused requests from the free package can’t be carried over to the next day.

In case of any issues, please contact us. Our goal is to provide the best level of support 24/7 and resolve our customers’ issues as quickly as possible. We aim to respond to new support requests within 8 hours and provide an update for existing ones for the next 12 hours on business days. Support during weekends is also available, but limited. If you have an urgent issue, please, reach out to our support team via Telegram.
