Simulate a Solana transaction before sending it via simulateTransaction (sigVerify off, recent blockhash replaced, nothing is sent): success or the exact error, compute units consumed, fee in lamports, program logs, return data. Pass ?tx= as base58 or base64 (unsigned is fine). Malformed tx -> 400, not charged.
