Passage Chain API

healthy 3,935 Subscribers

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.

Carbon API

Live on-chain data for Carbon (chain id carbon-1) — the Switcheo-built Cosmos-SDK Layer-1 for decentralised derivatives and spot trading, whose native token is SWTH — served directly from public LCD/REST nodes with multi-node failover. The status endpoint returns the latest block height and time, chain id, the staking bond denom and the current minting inflation rate. The validators endpoint lists the active bonded validator set ranked by stake, each with its moniker, operator address, self-plus-delegated SWTH, commission rate and jailed flag. The supply endpoint returns the total SWTH supply, the amount bonded in staking and the resulting bonded ratio. The governance endpoint returns the most recent on-chain proposals with their id, title, status and voting window. SWTH uses an 8-decimal base denomination which is converted to whole SWTH with exact big-integer scaling, and every figure is read live from the chain — nothing bundled or modelled — behind a short server-side cache with keep-warm so the feed stays fast and fresh. Ideal for staking dashboards, validator and delegator tooling, explorers, governance trackers and portfolio or analytics apps across the Cosmos and DeFi ecosystem. Live keyless upstream. 5 endpoints.

Fetch.ai API

Live on-chain data for Fetch.ai (chain id fetchhub-4) — the Cosmos-SDK Layer-1 behind the Artificial Superintelligence Alliance, whose native token is FET — served directly from public LCD/REST nodes with multi-node failover. The status endpoint returns the latest block height and time, chain id, the staking bond denom and the current minting inflation rate. The validators endpoint lists the active bonded validator set ranked by stake, each with its moniker, operator address, self-plus-delegated FET, commission rate and jailed flag. The supply endpoint returns the total FET supply, the amount bonded in staking and the resulting bonded ratio. The governance endpoint returns the most recent on-chain proposals with their id, title, status and voting window. FET uses an 18-decimal base denomination (afet) which is converted to whole FET with exact big-integer scaling, and every figure is read live from the chain — nothing bundled or modelled — behind a short server-side cache with keep-warm so the feed stays fast and fresh. Ideal for staking dashboards, validator and delegator tooling, explorers, governance trackers and portfolio or analytics apps across the Cosmos and AI-blockchain ecosystem. Live keyless upstream. 5 endpoints.

Oraichain API

Live on-chain data for Oraichain — the AI-oracle Layer-1 built on the Cosmos SDK, whose native token is ORAI — served directly from public LCD/REST nodes with multi-node failover. The status endpoint returns the latest block height and time, chain id, the staking bond denom and the current minting inflation rate. The validators endpoint lists the active bonded validator set ranked by stake, each with its moniker, operator address, self-plus-delegated ORAI tokens, commission rate and jailed flag. The supply endpoint returns the total ORAI supply, the amount bonded in staking and the resulting bonded ratio. The governance endpoint returns the most recent on-chain proposals with their id, title, status and voting window. Token amounts are converted from base micro-ORAI (6 decimals) into whole ORAI, and all figures are read live from the chain — nothing is bundled or modelled — with a short server-side cache and keep-warm so the feed stays fast and fresh. Ideal for staking dashboards, validator and delegator tooling, explorers, governance trackers and portfolio or analytics apps covering the Cosmos and AI-blockchain ecosystem. Live keyless upstream. 5 endpoints.

Sophon Chain API

Real-time on-chain data for Sophon (chain-id 50104), a ZK Layer-2 built on the zkSync Elastic Chain stack and focused on consumer and entertainment apps, where gas is paid in the native SOPH token. The status endpoint returns the chain id, network id, latest block height, native symbol and node client version so you can confirm the chain is live and synced. The block endpoint returns a block by decimal or 0x-hex height — or the latest block when no height is given — with its hash, parent hash, timestamp (raw and ISO), transaction count, gas used and limit, base fee and miner. The gas endpoint returns the current gas price in both wei and gwei at the latest block. The balance endpoint returns the native SOPH balance (in wei and human-readable units) and the transaction count (nonce) for any 0x address. The meta endpoint documents the chain id, decimals and ecosystem. Reads a live Sophon JSON-RPC node directly, so values are current to the latest block. Live, nothing stored. 5 endpoints. This serves native-coin and chain data; for ERC-20 token balances or contract calls use a dedicated token/contract API.
