Stacks Node RPC API
Direct RPC access to Stacks blockchain nodes for real-time data and operations.
Overview
The Stacks Node RPC API provides direct access to Stacks blockchain nodes through RPC endpoints. Hiro proxies these calls to upstream Stacks nodes - we don't maintain or control the nodes themselves, so performance and availability depend on upstream blockchain infrastructure.
Key features
- Raw blockchain node methods - Submit transactions, call read-only contracts, query mempool/state
- Real-time blockchain state - No caching layers, direct node responses
- Smart contract execution - Execute read-only functions and retrieve contract state
- Transaction broadcasting - Submit transactions directly to the network
Usage
Terminal
$curl -L 'https://api.hiro.so/v2/info' -H 'Accept: application/json'
For more usage examples and rate limiting information, see Usage.
REST vs RPC: Use Stacks Blockchain API for cached, indexed blockchain data (balances, transactions, events). Use RPC endpoints for raw node operations and real-time blockchain state queries.
