Retrieve detailed information about an Ethereum Beacon Chain validator. Use this tool to look up validator status, balance, activation epochs, slashing status, and other details. Supports lookup by validator index or BLS public key. Returns validator data including: current status (active_online, active_offline, pending, exiting, slashed, exited), balance in Gwei, activation/exit epochs, and withdrawal credentials.

Retrieve normalized attestation inclusion effectiveness for one or more validators. Use this tool to measure how effectively validators are getting their attestations included in the Beacon Chain. A score of 1.0 indicates perfect effectiveness (100% inclusion), while higher scores indicate lower effectiveness (max 2.0 for 0% inclusion). Supports lookup by validator index, BLS public key, or a mix of both (comma-separated, maximum 100 validators per request by default).

Retrieve attestations observed for one or more validators within a bounded epoch window. By default, returns data for the last 100 epochs. Use when you need to check validator attestation history, verify attestation performance, or analyze missed attestations.

Retrieve per-epoch balance history for one or more Ethereum Beacon Chain validators. Use optional query parameters to control the time window (latest_epoch, offset, limit). Returns an array of balance snapshots showing how validator balances changed over time, including both total balance and effective balance. Useful for tracking validator performance and generating historical balance charts.
