Ethereum Beacon Chain explorer workflows using the beaconcha.in API (V1 and V2). Use when the user mentions "validator", "beacon chain", "staking rewards", "attestation", "epoch", "slot", "beaconcha.in", "BeaconScore", "validator efficiency", "staking performance", "consensus layer", "CL rewards", "execution layer rewards", "validator balance", "validator status", "block proposal", "sync committee", "slashing", "validator queue", "activation queue", "exit queue", "withdrawal", "ETH staking", "validator dashboard", "validator monitoring", or asks to look up, monitor, analyze, or report on Ethereum validators or network health. Also use when the user provides a validator index, public key, or withdrawal address and wants data about it. Do NOT use for general Ethereum execution layer queries unrelated to staking or the beacon chain.
