Aptos REST API
Aptos Overview
Aptos is a Layer 1 blockchain built to support the widespread adoption of blockchain through better technology and user experience. It introduces a novel smart contract programming language called Move, designed to be safe, flexible, and expressive. Aptos leverages a parallel execution engine (Block-STM) to achieve high throughput and low latency, making it ideal for decentralized applications that require fast transaction processing.
The network features AptosBFT, a consensus protocol derived from HotStuff, which provides strong safety guarantees while maintaining high performance. Aptos also supports on-chain governance, enabling protocol upgrades and network evolution while preserving decentralization.
Interacting with Aptos's APIs
Aptos nodes expose a REST API interface that allows developers to interact with the blockchain using standard HTTP methods. This makes it easy to integrate Aptos functionality into web applications and mobile apps using familiar tools and libraries.
However, due to Aptos's unique architecture and the Move programming language, some API behaviors may differ from other blockchains. The QuickNode Aptos documentation is continuously evolving as the chain undergoes upgrades and changes, so we highly recommend cross-referencing with the official Aptos documentation for the latest updates and API differences.
Make Aptos API Calls
The quickest way to start building on Aptos is to create a QuickNode endpoint and send your first REST API request.
QuickNode provides managed Aptos endpoints, giving you immediate access to the Aptos network without the overhead of running infrastructure. These endpoints offer:
- High reliability – globally distributed infrastructure designed to minimize downtime
- Enhanced performance – optimized latency and request handling for production-grade apps
- Integrated ecosystem – additional functionality through specialized APIs (add-ons) on the QuickNode Marketplace and products like Streams
Visit the QuickStart page to create your endpoint and send your first request.
