API Overview

Query the Stacks blockchain, interact with smart contracts, and broadcast transactions with the Stacks Blockchain API, all via a familiar REST interface.

The Stacks Blockchain API expands the intentionally minimal RPC endpoints available in Stacks nodes and indexes, cleans, and enriches on-chain data to put everything you need at your fingertips. Who knew getting reliable blockchain data could be this easy?

Call smart contracts

Call a read-only public function on a smart contract.

Retrieve user information

Get information about a user, their account balance, transaction history, and more.
