Stacks REST API
What is Stacks?
Stacks is a Bitcoin Layer 2 for smart contracts and decentralized applications. It uses the Clarity smart contract language and the Proof of Transfer (PoX) mechanism to anchor security to the Bitcoin network. Developers build on Stacks to create applications that leverage Bitcoin’s security and finality while enabling expressive on-chain logic with Clarity.
Interacting with Stacks APIs
Stacks exposes both REST and WebSocket interfaces for programmatic access to the chain. You can query blocks, transactions, and accounts, read contract interfaces and call read‑only functions, inspect mempool and fees, and broadcast signed transactions.
Connect by running your own Stacks node with the API service enabled, or by using a hosted provider such as Quicknode, which offers reliable, low-latency access without the need to manage infrastructure.
The Quicknode Stacks documentation is continuously updated, but we recommend cross-referencing with the official Stacks documentation for the latest API details.
Make Stacks API Calls
The quickest way to start building on Stacks is to create a Quicknode endpoint and send your first request. Quicknode provides managed Stacks endpoints, offering:
- High reliability — globally distributed infrastructure designed to minimize downtime
- Enhanced performance — optimized latency and request handling for production-grade apps
