`POST /eth/v1/beacon/blocks`

Publishes a signed block.

Instructs the beacon node to broadcast a newly signed beacon block to the beacon network, to be included in the beacon chain. The beacon node is not required to validate the signed BeaconBlock, and a successful response (20X) only indicates that the broadcast has been successful. The beacon node is expected to integrate the new block into its state, and therefore validate the block internally, however blocks which fail the validation are still broadcast but a different status code is returned (202).

Parameters

Eth-Consensus-Version (header): a version of the block being submitted, if using SSZ encoding. Available values : phase0, altair, bellatrix.
<request body> (required): the SignedBeaconBlock object composed of the BeaconBlock object (produced by beacon node) and validator signature.

Request example

curl -X POST "https://rpc.ankr.com/premium-http/gnosis_beacon/YOUR_ANKR_API_KEY/eth/v1/beacon/blocks" \
-H "Eth-Consensus-Version: bellatrix" \
-H "Content-Type: application/json" \
-H "Accept: application/json" \
-d '{your_request_body}'

Responses

Code 200: The block was validated successfully and has been broadcast. It has also been integrated into the beacon node's database.
Code 202: The block failed validation, but was successfully broadcast anyway. It was not integrated into the beacon node's database.
Code 400: The SignedBeaconBlock object is invalid.

{
  "code": 400,
  "message": "Invalid block: missing signature"
}

Code 500: Beacon node internal error.

{
  "code": 500,
  "message": "Internal server error"
}

Code 503: Beacon node is currently syncing, try again later.

{
  "code": 503,
  "message": "Beacon node is currently syncing and not serving request on that endpoint"
}

`POST /eth/v1/beacon/blinded_blocks`

Publishes a signed block.

Instructs the beacon node to use the components of the SignedBlindedBeaconBlock to construct and publish a SignedBeaconBlock by swapping out the transactions_root for the corresponding full list of transactions. The beacon node should broadcast a newly constructed SignedBeaconBlock to the beacon network, to be included in the beacon chain. The beacon node is not required to validate the signed BeaconBlock, and a successful response (20X) only indicates that the broadcast has been successful. The beacon node is expected to integrate the new block into its state, and therefore validate the block internally, however blocks which fail the validation are still broadcast but a different status code is returned (202). Pre-Bellatrix, this endpoint will accept a SignedBeaconBlock.

Parameters

Eth-Consensus-Version (header): a version of the block being submitted, if using SSZ encoding. Available values : phase0, altair, bellatrix.
<request body> (required): the SignedBlindedBeaconBlock object composed of BlindedBeaconBlock object (produced by beacon node) and validator signature.

Request example

curl -X POST "https://rpc.ankr.com/premium-http/gnosis_beacon/YOUR_ANKR_API_KEY/eth/v1/beacon/blinded_blocks" \
-H "Eth-Consensus-Version: bellatrix" \
-H "Content-Type: application/json" \
-H "Accept: application/json" \
-d '{your_request_body}'

Responses

Code 200: The block was validated successfully and has been broadcast. It has also been integrated into the beacon node's database.
Code 202: The block failed validation, but was successfully broadcast anyway. It was not integrated into the beacon node's database.
Code 400: The SignedBlindedBeaconBlock object is invalid.

{
  "code": 400,
  "message": "Invalid block: missing signature"
}

Code 500: Beacon node internal error.

{
  "code": 500,
  "message": "Internal server error"
}

Code 503: Beacon node is currently syncing, try again later.

`GET /eth/v2/beacon/blocks/{block_id}`

Retrieves a block.

Retrieves block details for given block id. Depending on Accept header it can be returned either as json or as bytes serialized by SSZ.

Parameters

block_id (string; path; required): a block identifier. Can be one of: head (canonical head in node's view), genesis, finalized, <slot>, <hex encoded blockRoot with 0x prefix>.

Request example

curl -X GET "https://rpc.ankr.com/premium-http/gnosis_beacon/YOUR_ANKR_API_KEY/eth/v2/beacon/blocks/{block_id}" \
-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.
