  title: Solana Scan a Program's Owned Accounts
  summary: Verify an address is an executable program, list the accounts it owns, and batch-read the first of them.
  description: >-
    The discovery path for anyone indexing a Solana program's on-chain state.
    The workflow first reads the supplied address and confirms it is actually an
    executable program rather than a data account, then lists every account
    owned by that program in parsed form, and finally batch-reads the leading
    owned accounts in a single getMultipleAccounts call rather than one request
    per account. getProgramAccounts is one of the heaviest methods on the RPC
    surface and many public endpoints restrict or rate-limit it, which is
    exactly why the executable check comes first. Every step spells out its
    JSON-RPC request inline so the flow can be read and executed without opening
    the underlying OpenAPI description.

      Read the address and confirm the executable flag is set. Running a
      program-account scan against a non-program address wastes an expensive
      call and returns nothing useful.
