In this article we would like to help you to get started using the Ethereum search engine.

First of all, here are the benefits why you should get your free API key to use our database index:

  • Access Ethereum blockchain data really fast and in real-time with the latest blocks.

  • Maximum flexibility in regards to your search queries.

  • No need for your own archive node to set up and maintain.

Start using Ethereum data without losing precious developer time or any hidden expenses.


Step 1: Visit our website

On our website you can find general information about us, what we do and also our news articles. The FAQ section and especially the documentation might be helpful when you start querying our Ethereum data. Also, you will find a real-time status on our indexed chains.

To start your queries on our Ethereum blockchain search engine, you can use Elasticsearch and PostgreSQL. With Elasticsearch you will get as good results as with SQL, so pick whatever query language suits you best. Read about our reasoning to offer different options here “Query Ethereum with SQL”.

Besides the API key, you find the expiring date as valid until. The API key is per default valid for one year starting the day of your request. If you already know that you need it for a longer time period, you can easily create your own key (see below). Next to your API key you find a copy button to easily copy and paste the key to wherever you want to use it.

Start exploring blockchain data with your individual API key, valid for one year.

You can request a new API key by clicking CREATE NEW API KEY at any time.
You will be forwarded to a site where you can enter an individual name/description, an expiration date of your choosing as well as your domain address. After you click CREATE KEY, you will find your new key as shown in the picture above.
