  title: Bitcoin - Blockchain Indexer API
  description: >-
    This API provides core indexer endpoints with support for Bitcoin
    metaprotocols by delivering real-time, rollback-protected access to
    Bitcoin's UTXO data, enabling developers to build responsive and reliable
    blockchain applications without managing complex infrastructure.


    #### Key Features:

    - **Real-Time Data with Rollback Protection:** Ensures data accuracy by
    handling chain reorganizations gracefully, providing live data without
    sacrificing integrity.

    - **Comprehensive UTXO Indexing:** Specialized pipelines extract, match, and
    process on-chain information, including handling rollbacks, to provide
    accurate and up-to-date data.


    #### Key Benefits for Developers:

    By abstracting the complexities of blockchain data retrieval and processing,
    Maestro's Bitcoin Indexer API empowers developers to focus on building
    innovative applications with confidence in fast and reliable access to
    historical chain data.
