The Base API — build without running a node

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

Blockchain data

Read Base 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.

What makes Base blockchain different?

Base, an Ethereum L2 platform, ensures security, stability, and scalability for on-chain applications. Any EVM codebase can be deployed to allow onboarding users and assets from Ethereum L1, Coinbase, and other chains. Integration with existing tools thanks to EVM compatibility is made possible. Additionally, its rollup architecture reduces user costs by 10x.
