Ethereum Beacon Chain API Overview

Deprecated

Bitquery has stopped supporting the Ethereum Beacon Chain (ETH2) API. Historical data may still be available, but it is no longer updated. The schema reference below is preserved for archival purposes.

Bitquery provides APIs to access Eth2 data. You can get info on the ethereum's staking model. It uses the Proof-of-stake, a consensus method that blockchain networks utilize to reach distributed consensus.

These APIs provide details on validators, their staked amounts, their exits and so on. The easiest way to start is through the Beacon Chain Explorer

The Ethereum Beacon Chain is the proof-of-stake consensus layer: it coordinates validators, attestations, block proposals, deposits, voluntary exits, and slashings (including proposer slashings where applicable). It is not the execution layer where user transactions and smart contracts run—that data lives in the ethereum schema. Bitquery’s Beacon APIs focus on this consensus-side lifecycle and staking behavior.

What You Can Query​

  • Beacon blocks — slots, roots or identifiers, and linkage to the consensus timeline as exposed by the schema
  • Validators — participation in staking, balances, and state changes such as activation or exit
  • Attestations — votes that support checkpoints and chain head, for participation and finality-related analysis
  • Deposits — staking deposits that connect the economic security model to validator onboarding
  • Slashings — evidence of protocol violations, including proposer-related cases where indexed
  • Voluntary exits — validator-initiated exits from active duty as recorded on the Beacon Chain

Common Use Cases​

  • Staking dashboards — monitor validator counts, effective balances, and attestation participation over time
  • Risk and slashings — surface slashings and unusual validator behavior for operations or research
  • Consensus research — correlate deposits, exits, and beacon block progression without mixing in execution-layer DEX or NFT data
