  title: Solana Request a Devnet Airdrop and Confirm Funding
  summary: Check node health, record a balance, request an airdrop, confirm it, and verify the balance moved.
  description: >-
    The standard way to fund a development wallet. The workflow confirms the RPC
    node is healthy, records the starting lamport balance, requests an airdrop,
    polls the airdrop signature until it is confirmed, and re-reads the balance
    so the caller can prove the funds actually landed rather than trusting the
    signature alone. requestAirdrop is only served by the Devnet and Testnet
    clusters, so this flow must be run against a non-Mainnet server. Every step
    spells out its JSON-RPC request inline so the flow can be read and executed
    without opening the underlying OpenAPI description.
