Bitcoin RPC
Bitcoin Overview
Bitcoin is the world's first and most established cryptocurrency, operating as a decentralized peer-to-peer electronic cash system. Built on a proof-of-work consensus mechanism, Bitcoin provides:
- Digital Scarcity: A fixed supply of 21 million coins with predictable issuance
- Decentralized Network: Nodes worldwide maintaining network security
- Immutable Ledger: Cryptographically secured transaction history
- Global Settlement: 24/7 borderless value transfer without intermediaries
Bitcoin's architecture prioritizes security and decentralization, making it the foundation for digital value storage and transfer. The network processes transactions through miners who compete to solve cryptographic puzzles, securing the blockchain and earning Bitcoin rewards.
Interacting with Bitcoin's APIs
Bitcoin Core provides a comprehensive JSON-RPC API that enables developers to interact with the Bitcoin network programmatically. The API supports operations including transaction management, blockchain queries, and network monitoring.
Bitcoin's RPC interface follows standard JSON-RPC 2.0 protocols, making it compatible with most programming languages and development frameworks. However, Bitcoin's UTXO model differs significantly from account-based blockchains, requiring developers to understand transaction inputs and outputs.
Make Bitcoin API Calls
The quickest way to start building on Bitcoin is to create a QuickNode endpoint and send your first JSON-RPC request.
QuickNode provides managed Bitcoin endpoints, giving you immediate access to Bitcoin Mainnet and Testnet without the complexity of running your own Bitcoin node. These endpoints offer:
- High reliability – globally distributed infrastructure with 99.9% uptime SLA
- Enhanced performance – optimized for low latency with advanced caching layers
- Enterprise features – advanced analytics, debugging tools, and dedicated support
Visit the QuickStart page to create your endpoint and send your first request.
Supported Networks
QuickNode provides access to the following Bitcoin networks:
