Indexer

The Indexer API, Transaction Stream Service, and Custom Processors are currently in beta. Please report any problems you encounter by creating an issue in the [aptos-indexer-processors](https://github.com/aptos-labs/aptos-indexer-processors/issues/new/choose) repo.

Most applications require an indexer to efficiently query for on-chain state as the Aptos Node API provides only a basic, stable API and does not support data shaping required for rich user experiences. The Aptos Indexer processes raw blockchain data for app-specific needs, enabling low-latency and enhanced experiences for end-user applications.

Here’s an interactive example of how you can query for the Current Coin Balances of an account. More usage examples can be found in common queries.
