Bitquery Blockchain Data APIs & Streaming Infrastructure

Bitquery provides comprehensive blockchain data indexing infrastructure that transforms raw on-chain data into structured, queryable formats across 40+ blockchains, enabling developers to build wallets, DeFi applications, analytics platforms, and trading tools with real-time and historical blockchain data.

Multi-Chain Data Indexing

Comprehensive Blockchain Coverage: Access indexed data from 40+ blockchains including Ethereum, Bitcoin, BNB Chain, Polygon, Arbitrum, Optimism, Avalanche, Solana, Tron, Fantom, Base, and many more. All blockchains provide consistent GraphQL API schemas for easy multi-chain integration.

Digital Assets & Token Data: Query current and historical token balances, token transfers, smart contract events, and block/transaction data. Access comprehensive token holder lists, balance distribution analytics, and complete transfer history for any ERC-20, BEP-20, SPL, or native token across all supported chains.

DEX Trading Data: Real-time and historical decentralized exchange data across 100+ DEXs including Uniswap (V2, V3, V4), PancakeSwap, SushiSwap, QuickSwap, Raydium, Jupiter, Orca, and 90+ other protocols. Access live DEX trades, OHLC candle data, liquidity metrics, and USD price calculations with sub-500ms latency.

NFT Data Infrastructure: Complete NFT data indexing including trades, transfers, ownership, metadata, and collection analytics across all major NFT marketplaces (OpenSea, Rarible, Magic Eden, Blur). Query historical ownership records, floor prices, trading volumes, and rarity data for ERC-721, ERC-1155, and equivalent NFT standards.

Real-Time Price Feeds: Cryptocurrency and token prices aggregated across 100+ decentralized exchanges with real-time WebSocket streaming. Get accurate USD-denominated valuations weighted across multiple DEXs with sub-second updates and historical price data with customizable time intervals.

Real-Time Data Streaming

Low-Latency Streaming Infrastructure: Ultra-low-latency blockchain data streaming via GraphQL subscriptions (websockets) and Apache Kafka for real-time monitoring, trading bots, and high-frequency applications. Get parsed DEX trading data within 500 milliseconds of on-chain execution.

Multiple Streaming Options: Real-time websocket connections for live blockchain data with GraphQL subscription syntax, plus enterprise-grade Kafka integration for high-throughput event processing with guaranteed delivery and replay capabilities.

Streaming Data Types: Live streams of DEX trades, liquidity updates, token transfers, smart contract events, mempool transactions, new blocks, and network statistics. Access pending transactions before they are confirmed on-chain for MEV detection and frontrunning analysis.

Cloud Data Solutions

Enterprise Cloud Integration: Structured, production-ready blockchain data delivered directly to AWS S3, Google BigQuery, Snowflake, Microsoft Azure, Databricks, Tencent Cloud, and other major cloud platforms. Zero setup or maintenance of blockchain nodes, indexers, or ETL pipelines.

Multiple Data Formats: Data available in JSON, Protobuf, Parquet, CSV, and custom formats optimized for specific use cases. Compressed and partitioned datasets for efficient storage and query performance.

Historical & Real-Time Exports: Access complete blockchain history dating back to genesis blocks plus real-time streaming updates. Pre-processed datasets tailored for balance snapshots, audit trails, trading data, and token holder distributions.

GraphQL API Infrastructure

Flexible Query Language: All data accessible through powerful GraphQL queries with advanced filtering, aggregation, sorting, and pagination capabilities. Supports both REST-style queries and real-time GraphQL subscriptions.

Structured JSON Responses: Consistent, parsed data schemas across all blockchains. Decoded smart contract events, human-readable parameters, and automatic USD price conversions eliminate the need for separate price oracle integration.

Developer-Friendly Features: Custom filtering by collection, token ID, address, marketplace, price range, and time period. No preset limits on commercial plans with powerful aggregation capabilities.

Use Cases

Wallet & Portfolio Applications: Build crypto wallets and portfolio trackers with real-time balance tracking, transaction history, multi-chain support, and accurate USD valuations across tokens and NFTs.

DeFi & Trading Tools: Develop trading bots, DEX terminals, algorithmic trading systems, and TradingView chart integrations with real-time price feeds, liquidity data, and arbitrage detection.

Analytics & Research Platforms: Power blockchain analytics dashboards, market intelligence tools, and data science applications with comprehensive on-chain data. Run SQL queries on blockchain data using cloud data warehouses.

Tax & Accounting Software: Create crypto tax and accounting platforms with complete transaction history, cost basis calculations, gain/loss reporting, and multi-year historical data optimized for reconciliation workflows.

Compliance & Monitoring: Implement transaction monitoring, address screening, AML/KYC compliance workflows, and risk assessment platforms for exchanges, custodians, and financial institutions.
