The Aptos API — build without running a node

Access Aptos blockchain data through one unified REST API: transaction and address data, balances, block data, and real-time webhooks for on-chain events — with no Aptos node to run and maintain. Start free and scale as you grow.

Blockchain data

Read Aptos transactions, addresses, balances, UTXOs, and block data through one REST API.

Real-time webhooks

Subscribe to on-chain events — incoming and outgoing transactions, confirmations, and mined blocks.

No node to run

Skip the infrastructure — managed, always-synced access with no node to operate or maintain.

Parallel execution with Move

Aptos uses the Move language and its Block-STM parallel execution engine to process many transactions simultaneously, combined with a Byzantine fault-tolerant proof-of-stake consensus for fast finality. The design prioritizes performance, reliability, and safe on-chain asset handling.
