# aws-sdk-managedblockchainquery Amazon Managed Blockchain (AMB) Query provides you with convenient access to multi-blockchain network data, which makes it easier for you to extract contextual data related to blockchain activity. You can use AMB Query to read data from public blockchain networks, such as Bitcoin Mainnet and Ethereum Mainnet. You can also get information such as the current and historical balances of addresses, or you can get a list of blockchain transactions for a given time period. Additionally, you can get details of a given transaction, such as transaction events, which you can further analyze or use in business logic for your applications. ## Getting Started > Examples are available for many services and operations, check out the > [examples folder in GitHub](https://github.com/awslabs/aws-sdk-rust/tree/main/examples). The SDK provides one crate per AWS service. You must add [Tokio](https://crates.io/crates/tokio) as a dependency within your Rust project to execute asynchronous code. To add `aws-sdk-managedblockchainquery` to your project, add the following to your **Cargo.toml** file: ```toml [dependencies] aws-config = { version = "1.1.7", features = ["behavior-version-latest"] } aws-sdk-managedblockchainquery = "1.37.0" tokio = { version = "1", features = ["full"] } ``` Then in code, a client can be created with the following: ```rust,no_run use aws_sdk_managedblockchainquery as managedblockchainquery; #[::tokio::main] async fn main() -> Result<(), managedblockchainquery::Error> { let config = aws_config::load_from_env().await; let client = aws_sdk_managedblockchainquery::Client::new(&config); // ... make some calls with the client Ok(()) } ``` See the [client documentation](https://docs.rs/aws-sdk-managedblockchainquery/latest/aws_sdk_managedblockchainquery/client/struct.Client.html) for information on what calls can be made, and the inputs and outputs for each of those calls. ## Using the SDK Until the SDK is released, we will be adding information about using the SDK to the [Developer Guide](https://docs.aws.amazon.com/sdk-for-rust/latest/dg/welcome.html). Feel free to suggest additional sections for the guide by opening an issue and describing what you are trying to do. ## Getting Help * [GitHub discussions](https://github.com/awslabs/aws-sdk-rust/discussions) - For ideas, RFCs & general questions * [GitHub issues](https://github.com/awslabs/aws-sdk-rust/issues/new/choose) - For bug reports & feature requests * [Generated Docs (latest version)](https://awslabs.github.io/aws-sdk-rust/) * [Usage examples](https://github.com/awslabs/aws-sdk-rust/tree/main/examples) ## License This project is licensed under the Apache-2.0 License.
