  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.

    fetches the same block addressed explicitly by its height value.
