To enable this use case, the `BLOCK_V2` request type of the `/api/v1/eth2/sign/{identifier}` endpoint is extended with an additional array field named `proofs`. The array consists of objects with the properties `index`, `proof` and `value`, where `index` is an arbitrary [generalized index](https://github.com/ethereum/consensus-specs/blob/v1.4.0-beta.1/ssz/merkle-proofs.md#generalized-merkle-tree-index) of any property nested under the block body and `proof` is its corresponding Merkle proof against the block body root included in the request.
