  title: Pocket Network Shannon Block Explorer
  summary: Read the latest Shannon block height, then fetch that exact block by height.
  description: >-
    A minimal block-explorer flow for the Pocket Network Shannon chain. It first
    reads the most recently committed CometBFT block from the Cosmos REST
    surface to learn the current chain height, then re-fetches the block at that
    specific height so a consumer has a stable, height-addressed copy of the
    block. Each step spells out its request inline so the flow can be read and
    executed without opening the underlying OpenAPI description.

  summary: Resolve the latest Shannon height and fetch the block at that height.

    Reads the latest committed block to discover the current height, then
    fetches the same block addressed explicitly by its height value.
