Overview

Bitquery 's infrastructure provides you access to historical and real-time blockchain data through four routes: the GraphQL API, streams (WebSocket, Kafka, and gRPC on Solana), Parquet exports from the Bitquery Data Store, and the raw Blockchain Data Lake.

GraphQL Query API

Get started with our APIs in a minute by building your first query.

You can query archive, real-time or combined dataset based on your requirements.

After the query is built you can save it and embed it in your application using pre-cooked code snippet in any popular programming language.

query {
  EVM(dataset: archive network: bsc) {
    Transactions {
      Block {
        Date
      }
      count
    }
  }
}

Integrated Development Environment (IDE)

Integrated Development Environment (IDE) helps you to manage your query, share them with other developers and generate a code to use the queries in your applications.

GraphQL Subscription (WebSocket) API

Subscription (WebSocket) is an extension of GraphQL API. It allows to subscribe on the updates in the data in real-time and receive the new data changes using WebSocket protocol.

Protocols subscriptions-transport-ws and graphql-transport-ws are supported.

subscription {
  EVM(trigger_on: head) {
    Transactions {
      Block {
        Hash
        Number
        Date
      }
      count
    }
  }
}

Ways to Get Data

API

GraphQL queries and WebSocket subscriptions. You get both realtime and historical data. How far back it goes depends on the chain. See Data Coverage & Retention.

Streams

Live data over WebSocket subscriptions, Kafka, or gRPC on Solana. See Streams and Solana gRPC (CoreCast).

Data Store Exports

Parsed Parquet datasets, including history older than the API window. You download them from S3 or Cloudflare R2, or get them delivered to your own bucket or warehouse as a custom export. Buy them on the Bitquery Data Store. See Data Store exports.

Data Lake

Raw Protobuf blocks over S3. You decode them and parse them your own way. See Blockchain Data Lake.

SQL Like Interface

We also provide SQL like interface on our Enterprise plan, if you want to explore that, please send us email at hello@bitquery.io

Bitquery Support Channels

We highly encourage you to dig into our docs first; however, you can contact us on the following platforms if you still have any queries.

1. Telegram - For quick questions and doubts
2. Community Forum - For how to questions, features requests that can also help wider community
3. Support Desk - For data problems, bugs
