Events

`GET /eth/v1/events`

Subscribes to Beacon node events.

Provides endpoint to subscribe to beacon node Server-Sent-Events stream. Consumers should use eventsource implementation to listen on those events.

Servers may send SSE comments beginning with : for any purpose, including to keep the event stream connection alive in the presence of proxy servers.

Parameters

topics (array[string]; query; required): event types to subscribe to; available values : head, block, attestation, voluntary_exit, finalized_checkpoint, chain_reorg, contribution_and_proof.

Request example

curl -X GET "https://rpc.ankr.com/premium-http/gnosis_beacon/YOUR_ANKR_API_KEY/eth/v1/events" \

The node has finished processing, resulting in a new head. previous_duty_dependent_root is get_block_root_at_slot(state, compute_start_slot_at_epoch(epoch - 1) - 1) and current_duty_dependent_root is get_block_root_at_slot(state, compute_start_slot_at_epoch(epoch) - 1). Both dependent roots use the genesis block root in the case of underflow.

`GET /eth/v1/node/health`

Retrieves health check.

Returns node health status in http status codes. Useful for load balancers.

Parameters

None.

Request example

curl -X GET "https://rpc.ankr.com/premium-http/gnosis_beacon/YOUR_ANKR_API_KEY/eth/v1/node/health"

Responses

Code 200: Node is ready.

Code 503: Node not initialized or having issues.

Validator

`POST /eth/v1/validator/duties/attester/{epoch}`

Retrieves attester duties.

Requests the beacon node to provide a set of attestation duties, which should be performed by validators, for a particular epoch. Duties should only need to be checked once per epoch, however a chain reorganization (of > MIN_SEED_LOOKAHEAD epochs) could occur, resulting in a change of duties. For full safety, you should monitor head events and confirm the dependent root in this response matches:

event.previous_duty_dependent_root when compute_epoch_at_slot(event.slot) == epoch
event.current_duty_dependent_root when compute_epoch_at_slot(event.slot) + 1 == epoch
event.block otherwise

The dependent_root value is get_block_root_at_slot(state, compute_start_slot_at_epoch(epoch - 1) - 1) or the genesis block root in the case of underflow.

Parameters

epoch (string; path; required): should only be allowed one epoch ahead.

`GET /eth/v1/validator/duties/proposer/{epoch}`

Retrieves block proposer duties.

Request beacon node to provide all validators that are scheduled to propose a block in the given epoch. Duties should only need to be checked once per epoch, however a chain reorganization could occur that results in a change of duties. For full safety, you should monitor head events and confirm the dependent root in this response matches:

event.current_duty_dependent_root when compute_epoch_at_slot(event.slot) == epoch
event.block otherwise

The dependent_root value is get_block_root_at_slot(state, compute_start_slot_at_epoch(epoch) - 1) or the genesis block root in the case of underflow.

Parameters

epoch (string; path; required); an epoch.

`POST /eth/v1/validator/duties/sync/{epoch}`

Retrieves sync committee duties.

Parameters

epoch (string; path; required): epoch // EPOCHS_PER_SYNC_COMMITTEE_PERIOD <= current_epoch // EPOCHS_PER_SYNC_COMMITTEE_PERIOD + 1

`GET /eth/v1/validator/blocks/{slot}`

Produces a new block, without signature.

Requests a beacon node to produce a valid block, which can then be signed by a validator.

Metadata in the response indicates the type of block produced, and the supported types of block will be added to as forks progress.

Parameters

slot (string; path; required): the slot for which the block should be proposed.
randao_reveal (string; hex; query; required): the validator's randao reveal value.
graffiti (string; hex; query): an arbitrary data validator to include in the block.

Request example

curl -X GET "https://rpc.ankr.com/premium-http/gnosis_beacon/YOUR_ANKR_API_KEY/eth/v1/validator/blocks/{slot}" \
-H "Accept: application/json"

Responses

Code 200: Success.

Note: The Eth-Consensus-Version header is required in response so client can deserialize returned json or ssz data more effectively.

`GET /eth/v1/validator/blinded_blocks/{slot}`

Produces a new blinded block, without signature.

Requests a beacon node to produce a valid blinded block, which can then be signed by a validator. A blinded block is a block with only a transactions root, rather than a full transactions list.

Metadata in the response indicates the type of block produced, and the supported types of block will be added to as forks progress.

Pre-Bellatrix, this endpoint will return a BeaconBlock.

Parameters

slot (string; path; required): the slot for which the block should be proposed.
randao_reveal (string; hex; query; required): the validator's randao reveal value.
graffiti (string; hex; query): an arbitrary data validator to include in the block.

Request example

curl -X GET "https://rpc.ankr.com/premium-http/gnosis_beacon/YOUR_ANKR_API_KEY/eth/v1/validator/blinded_blocks/{slot}" \
-H "Accept: application/json"

Responses

Code 200: Success.

`POST /eth/v1/validator/beacon_committee_subscriptions`

Signals the Beacon node to prepare for a committee subnet.

After beacon node receives this request, search using discv5 for peers related to this subnet and replace current peers with those ones if necessary. If validator is_aggregator, beacon node must:

Announce subnet topic subscription on gossipsub.
Aggregate attestations received on that subnet.

Parameters

Responses

Code 200: Success. Slot signature is valid and beacon node has prepared the attestation subnet.

Note that we cannot be certain the Beacon node will find peers for that subnet for various reasons.
