In Web3, contrary to Web2, where all interactions between the user and application are guarded, the blockchain is public and accessible to anyone. Every data point piques the curiosity of analysts.
Web3 apps and experiences can be built using blockchain APIs, which provide developers with blockchain data and tools. These APIs aim to simplify the interaction between different blockchains and platforms so that developers don’t have to worry about complex technical details when developing their applications.
You can create dashboards or data visualizations using bitcoin chain data. You can build a better version of a project by studying how users interact with decentralized exchanges. You can read about the project’s traction and decide whether or not to invest.

Anyone with a basic understanding of SQL or the desire to learn it can access a real-time balance sheet, network traction, user engagement, and retention, or a comprehensive risk analysis.
A computer, referred to as a node, runs the software that connects it to the blockchain network to collect the on-chain data. It enables them to communicate between nodes and store transaction data. Anyone can run a node and see what is going on — it is open and transparent.
Many businesses use node infrastructure at scale and make blockchain data available via an API.
There are quite a few blockchain api providers in the market. For any developer who is interested, we have researched and listed some of the best blockchain API providers in the market today.
Bitquery is one of the best blockchain data providers in this space. Bitquery extracts and presents valuable data from over 40 blockchains using actionable, insightful blockchain GraphQL APIs. The tool is for everyone, including developers who use Bitquery’s blockchain APIs and Widgets to build projects and publications, as well as financial organizations and banks, to reduce fraud, analyze risks, and improve security.
Bitquery houses different products for different purposes:
- Cryptocurrency Forensics with Coinpath API: Coinpath is a set of blockchain money tracing APIs based on a sophisticated mathematical algorithm capable of performing complex calculations between blockchain addresses to visualize transactions and blockchain money flow. Using Coinpath and an example of FairWin’s collapse in 2019, this article shows how to conduct an investigation.
- DEX APIs: Real-time trades across various DEX protocols and blockchains are made possible by our DEX GraphQL APIs. Trade data is available for protocols like PancakeSwap, Kyber, Uniswap, 0x, Balancer Protocol, and others. Bitquery support 100+ DEXs on 10+ blockchains.
- The transaction API is available for low-level transaction analysis. What are the assets that are driving transaction volume? What is the daily transaction volume trend? How has it changed over time? Is there a peak in transaction volume during the day? You can highlight a specific token event that occurred on a specific date or time frame, outlining the exact transaction flow. What is the most recent block? How long did it take to make, and what transactions does it contain? Curious about a whale?
- Bitquery widgets simplify the display of blockchain analytics, DApp, and DeFi data on your website. These widgets are interactive, and users can change the queries to view different data sets independently. Using the Tradingview library, you can create your live charting application.
The Graph is an indexing protocol that organizes all data so that networks like Ethereum can be queried. It enables you to query difficult-to-query data as well as build and publish open APIs known as subgraphs. The Graph is useful for a blockchain data developer, indexer, or curator and currently includes three products: Subgraph Studio, the Graph Explorer for exploring subgraphs, and the Hosted Service for creating and exploring subgraphs.
