Polkadot & Kusama Governance (OpenGov) API

degraded 4,080 Subscribers

Polkadot and Kusama OpenGov, live from the public Polkassembly API — no key, nothing cached. OpenGov is a fully on-chain governance system: anyone can submit a referendum on a governance track, it accrues aye / nay / abstain votes weighted by conviction-locked DOT or KSM, and treasury referenda spend on-chain funds to beneficiaries. There is no other Polkadot reader in the marketplace; this opens the governance layer. List the most recent referenda for a network with their governance track, status and proposer. Read a single referendum in full — its aye / nay / support tally converted from Planck to DOT/KSM, its status, track, requested treasury amount and proposer. And surface the referenda that are currently open for voting (Deciding / Confirming / Submitted / Preparing) so wallets and delegates can act. Works for both Polkadot and Kusama through the network parameter. The OpenGov layer for Polkadot/Kusama wallets, governance dashboards, delegates and analytics. Live from api.polkassembly.io.

Moonbeam API

Real-time on-chain data for Moonbeam (chain-id 1284) — the Ethereum-compatible smart-contract parachain on Polkadot, fully EVM-compatible with GLMR as its native token. Query live network status (latest block height, network id, client version), fetch any block by height or the latest one (timestamp, transaction count, gas used / limit, base fee, miner), read the current gas price in wei and gwei, and look up the native GLMR balance and transaction count of any address. A keyless, no-account JSON wrapper over the canonical Moonbeam JSON-RPC node — decoded from hex into plain decimals and human-readable GLMR so you do not have to. Ideal for explorers, wallets, dashboards, gas estimators and analytics on Moonbeam.

Moonriver API

Real-time on-chain data for Moonriver (chain-id 1285) — the Ethereum-compatible companion network to Moonbeam, deployed on Kusama, with MOVR as its native token. Query live network status (latest block height, network id, client version), fetch any block by height or the latest one (timestamp, transaction count, gas used / limit, base fee, miner), read the current gas price in wei and gwei, and look up the native MOVR balance and transaction count of any address. A keyless, no-account JSON wrapper over the canonical Moonriver JSON-RPC node — decoded from hex into plain decimals and human-readable MOVR so you do not have to. Ideal for explorers, wallets, dashboards, gas estimators and analytics on Moonriver.

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.
