Passage Chain API

Real-time on-chain data for Passage (chain-id passage-2), a Cosmos-SDK Layer-1 for gaming, the metaverse and NFTs, with PASG as its native coin, secured by delegated proof-of-stake. The status endpoint returns the chain id, latest block height and time, proposer and node application version so you can confirm the chain is live and producing blocks. The validators endpoint returns the full bonded validator set — each moniker, operator address, stake in PASG, commission rate and jailed flag — sorted by stake, plus the total bonded and not-bonded PASG. The supply endpoint returns the total PASG supply (in PASG and base upasg), the bonded amount and the bonded ratio. The governance endpoint returns the most recent on-chain governance proposals with title, status and voting window. The meta endpoint documents the chain, denom and decimals. Reads a live Passage Cosmos-SDK LCD node directly (with mirror fallback), so values are current to the latest block. Live, nothing stored. 5 endpoints. This serves chain-level staking, supply and governance data; for individual NFTs or game assets use a dedicated indexer API.
