Example use cases

Prefer this endpoint when you need direct, low-latency access to Solana on-chain data (accounts, transactions, blocks, tokens) on a pay-per-call basis without committing to a subscription RPC plan. Ideal for agents that need occasional or burst Solana queries without managing API keys or monthly quotas.
