Data API: Base – On-Chain Data, NFTs, and DeFi

We’re thrilled to announce that Base, the Ethereum Layer 2 chain incubated by Coinbase, is now supported in Tatum’s Data API! Base offers fast, low-cost, and secure transactions, making it an ideal environment for scalable dApps and seamless on-chain experiences.

With this integration, developers can now query on-chain data from Base using Tatum’s unified Data API endpoints. From wallet portfolios and NFT balances to DeFi blocks and transaction histories, Tatum makes it easy to build data-driven blockchain applications on Base – without managing complex infrastructure.

Available Data API endpoints for Base:
