Blockchain Data

Get access to unified Blockchain Data using REST APIs. Starting from the genesis block, the whole data is synced into a well-designed, perfectly indexed, and fast database. Blockchain Data like balances, transactions, blocks, internal transactions, tokens transfers, etc. can be delivered on-demand for the average response time of 25 ms.

Blockchain Data


  • Top Blockchain Protocols have different data structures. Integrating them requires the allocation of development resources separately for everyone.
  • The nodes of different blockchain protocols are huge. In addition to the needed time for syncing there is a huge monthly hosting bill.
  • Some of the data can't be just queried from nodes like the internal transactions in Ethereum, balances of Bitcoin addresses, or fee data based on Mempool.


  • Unified, synced, and indexed data from top blockchain protocols, where more protocols are constantly integrated.
  • Why should everyone pay for their nodes separately when we can all use shared economy and save huge development and hosting costs.
  • Create and Check wallets, balances, addresses and contracts.

    Businesses like ours can easily get frustrated when the search for a third-party provider proves fruitless. Crypto APIs were like a breath of fresh air - they have the best support team I have ever seen, provide a great variety of products to get access to blockchain and market data, set up notifications, and more, all with an easy integration that doesn’t take more than a day.

    By using Crypto APIs we overcame a vicious cycle where we constantly had issues with hosting, support, and nodes, where we constantly paid other providers to use better features but that never happened. Now we use the functionality we actually need without compromising our security and saved a lot of costs. I Highly recommend Crypto APIs!

    We were facing issues with huge developments and uncomfortably high infrastructure costs, which at the time seemed like they would never end. Making the decision to switch our provider to Crypto APIs has been one of the best business moves I’ve made in my career. Now we get blockchain data, transaction notifications, accurate exchange rates, and more by using just one SDK and one subscription from the same service provider.

    Crypto APIs do a really good job! It's really great how quick and effective their APIs are. With their help, we have accelerated and improved our development and scaling processes. Their support was excellent and really helpful to our growth.


  • Unified Data

    Unified data is a new way of representing blockchain data. Utilized by Crypto APIs, the idea is to always have the exact same request and same response no matter the Blockchain. The integration is done in hours and adding new blockchains no longer needs any extra effort.

  • Fee Recommendations

    Obtain fee recommendations based on Mempool data. Calculations are done in real time and provide higher accuracy than fees based on already mined blocks. Using this endpoint customers can get gas price for Ethereum, fee per byte for Bitcoin, etc.

  • UTXOs

    Using the Unspent Transaction Outputs (UTXO) Endpoint you can get the unspent transaction outputs by address for all UTXO based protocols we support: Bitcoin, Bitcoin Cash, Doge, Dash, Litecoin.

  • Mempool Data

    Mempool data is very important as tens of thousands of pending transactions are fighting to be mined in the next block. Every transaction wants to be confirmed as soon as possible using the lowest fee possible.

  • HD Wallets (xPub, yPub, zPub)

    In addition to Blocks, Addresses, Balances, Transactions, Uncles, Smart Contracts, Tokens Transfers, Internal Transactions, Logs, etc., we also provide unified endpoints for syncing HD Wallets (xPub, yPub, zPub). Once synced, you can get balance, transactions and addresses.
