 5      Retrieve specification configuration used on this node.  The configuration should include:
 6        - Constants for all hard forks known by the beacon node, for example the [phase 0](https://github.com/ethereum/eth2.0-specs/blob/dev/specs/phase0/beacon-chain.md#constants) and [altair](https://github.com/ethereum/eth2.0-specs/blob/dev/specs/altair/beacon-chain.md#constants) values
 7        - Presets for all hard forks supplied to the beacon node, for example the [phase 0](https://github.com/ethereum/eth2.0-specs/blob/dev/presets/mainnet/phase0.yaml) and [altair](https://github.com/ethereum/eth2.0-specs/blob/dev/presets/mainnet/altair.yaml) values
 8        - Configuration for the beacon node, for example the [mainnet](https://github.com/ethereum/eth2.0-specs/blob/dev/configs/mainnet.yaml) values
 9  
10      Values are returned with following format:
11        - any value starting with 0x in the spec is returned as a hex string
12        - numeric values are returned as a quoted integer
