Every endpoint accepts an optional format=llm parameter that returns a natural-language sentence instead of structured JSON.
Tells you whether a given Solana validator is currently delinquent. Useful for an agent managing stake that needs to decide where to delegate, or whether to withdraw in a hurry.
