Information about the currently active constitutional committee When `is_dissolved` is `true`, the committee has been removed by an enacted `NoConfidence` governance action; `quorum` and `members` still describe the last seated committee for historical reference.

Votes cast under a given constitutional committee credential. Accepts both the CIP-129 hot bech32 (`cc_hot1...`) and the cold bech32 (`cc_cold1...`). When queried by a cold credential, this returns votes cast by any hot key that the cold key has authorized over time (so the result aggregates across hot-key rotations).

History of all votes cast by constitutional committee members across all committees (current and past). Not scoped to the currently active committee.

Return the information about Delegate Representatives (DReps)

DRep information.

Return the information about Proposals

Proposal information.

Proposal metadata information.

Parameters proposal details.

History of Proposal votes.

Withdrawal proposal details.

Proposal information.

Proposal metadata information. If this endpoint returns `404` or empty metadata for a known proposal, the off-chain metadata could not be fetched (e.g. unreachable URL or hash mismatch). Use the [`/governance/proposals/{gov_action_id}/metadata`](#tag/cardano--governance/GET/governance/proposals/{gov_action_id}/metadata) variant instead — it always returns the anchor `url` and `hash` along with an `error` object describing the fetch failure, so you can retrieve the metadata manually if needed.

Parameters proposal details.

History of Proposal votes.

Withdrawal proposal details.

Return backend status as a boolean. Your application should handle situations when backend for the given chain is unavailable.
