%% WARNING: DO NOT EDIT, AUTO-GENERATED CODE! %% See https://github.com/aws-beam/aws-codegen for more details. %% @doc 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.
