Blockchain Data

A Data API provides structured access to blockchain data, allowing developers to retrieve tokens, collections, balances, transactions, and DeFi activity without having to manually parse blocks or maintain custom indexers. These APIs are designed to simplify blockchain data queries and deliver normalised, ready-to-use information.

Skip the hassle of running your own indexers

Data APIs simplify blockchain development by eliminating the need to parse blocks or maintain custom indexing infrastructure. They save time and resources while giving developers instant access to accurate data for tokens, NFTs, balances, UTXOs, fees, and DeFi activity.

Why use Data API?

Unified Blockchain Data Access

With Data APIs, you can easily retrieve tokens, NFTs, balances, transactions, UTXOs, and DeFi events from different blockchains using a standardised interface. This eliminates the need to manage multiple node integrations or blockchain-specific quirks.

Build Insights and Analytics

Data APIs allow you to build analytics dashboards, wallet explorers, or monitoring tools by pulling structured information like token balances, portfolio history, or transaction records.

Automate Workflows

Integrating blockchain data directly into your application lets you automate workflows such as portfolio tracking, balance monitoring, or fee estimation, reducing manual overhead.

DeFi and NFT Ready

Data APIs include endpoints to fetch DeFi protocol events, NFT metadata, ownership, and collections. This makes it easy to integrate DeFi and NFT features into your applications without maintaining a dedicated indexer.

Efficient Resource Utilisation

Instead of querying raw nodes repeatedly, Data APIs deliver only the relevant blockchain data you need. This improves performance and reduces infrastructure costs.

Improved User Experience

By providing your users with instant access to balances, transactions, and asset insights, you enhance engagement and deliver a seamless Web3 experience.
