Pay-to-Public-Key (P2PK)

protocol.p2pk

Legacy output type that locks coins directly to a full public key and spends them with a matching signature. It is simpler than P2PKH, but it reveals the recipient public key at receive time and mainly matters today as an early script template reference point.
