Blockstream Explorer API

The Blockstream Explorer API is a high-performance API service that enables developers to search and retrieve data from both the Bitcoin and Liquid Network blockchains. This enterprise-grade infrastructure provides reliable access to blockchain data for applications, analytics platforms, and business intelligence systems.

Features and Capabilities

Comprehensive Blockchain Data Access: The API provides complete access to Bitcoin and Liquid blockchain data, including block information, transaction details, address histories, UTXO sets, and mempool contents. Developers can query historical and real-time data with low latency and high reliability.

Multi-Chain Support: Unlike single-chain explorers, the Blockstream Explorer API supports both Bitcoin mainnet and the Liquid Network, enabling applications that span both networks. This unified interface simplifies development for solutions leveraging both Bitcoin's security and Liquid's speed and privacy features.

Production-Grade Performance: Built on Blockstream's proven infrastructure that secures billions in digital assets, the API offers enterprise SLAs, redundant architecture for high availability, optimized indexing for fast queries, and WebSocket support for real-time updates.

Technical Specifications

RESTful API design with comprehensive documentation, JSON response format for easy integration, rate limiting and authentication for production use, and support for batch queries to minimize overhead. The API includes endpoints for blocks, transactions, addresses, assets (Liquid), and network statistics.

Use Cases

The Explorer API serves blockchain applications requiring reliable data feeds, cryptocurrency wallets needing transaction history and UTXO data, analytics platforms building market intelligence tools, compliance systems tracking blockchain activity, and DEX and DeFi protocols requiring on-chain data verification.

Developer Resources

Blockstream provides extensive documentation, code examples in multiple languages, client libraries and SDKs, and support for developers building on the platform. The public explorer at blockstream.info demonstrates the API's capabilities and serves as a reference implementation.
