Why Bitquery?

Detailed Ethereum API Documentation

Our Ethereum API documentation provides detailed guidance on accessing Ethereum transaction data, including insights into gas prices and methods to decode transaction data for optimal analysis.

Most Comprehensive Ethereum APIs

Regarded as the best Ethereum API, Bitquery offers comprehensive tools for developers, encompassing Ethereum wallet API, transaction API, and precise data on Ethereum's on-chain activities and mempool status.

Support for Ethereum NFTs

Specializing in NFTs, the Ethereum NFT API, combined with the Ethereum Web3 API, allows seamless integration and management of NFT assets alongside robust smart contract functionalities.

Enriched Smart Contract Data

Our ETH API allows you to get access complete smart contract traces, enabling users to query every detail of smart contracts on the Ethereum blockchain.

Ethereum Json RPC API alternative

JSON RPC is not optimal for bulk data retrieval from a blockchain. Instead, consider using Bitquery's API, supported by an indexed blockchain data warehouse.

Ready to build
next-generation infrastructure


Bitquery offers a broad selection of blockchains to get data for. The complex raw data is available in different levels of detail and from different viewpoints - whether we need simple, aggregated transfers or parameters for failed contract calls. The support is very responsive, friendly and quick to help.
