  title: QuickNode Key-Value Store REST API
  description: >-
    The QuickNode Key-Value Store REST API provides a managed, large-scale
    key-value storage service accessible over HTTP. Developers can create
    namespaces (databases), write and read keys, batch-load data, and
    delete keys, making it suitable for storing onchain-related metadata,
    indexer state, and application configuration alongside QuickNode's
    blockchain infrastructure. Authentication uses an API key issued from
    the QuickNode dashboard.
