Spark Protocol API

healthy 3,557 Subscribers

Live protocol metrics for Spark (the Sky / former MakerDAO ecosystem capital-allocation protocol), keyless. Both Spark products: SparkLend, the lending money-market with per-asset supply APY and TVL, and Spark Savings, the sUSDS / USDS / USDC / USDT savings products passing through the Sky Savings Rate — a savings-yield dimension other lending APIs do not have. Plus total value locked and per-chain TVL. One combined overview endpoint snapshots it all. Live, nothing stored. The Spark-metrics layer for DeFi dashboards, lending, savings, stablecoin and yield apps — distinct from pure lending protocols, this is Spark lending-plus-savings model specifically.

MakerDAO / Sky Governance API

MakerDAO / Sky governance — the original DeFi governance — live from the public governance-portal API, no key, nothing cached. Maker governs through three instruments: on-chain executive votes ("spells") that change the protocol and accrue MKR support, signal polls that gauge community sentiment, and recognized MKR delegates who vote on behalf of holders. The Sky reader covers the savings rate and protocol stats, but not governance; this opens it. List the executive votes with their MKR support and whether they have been executed. Browse the governance polls with the portal's own active / finished tally and each poll's type, voting window, tags and options. And rank the recognized delegates by delegated MKR with their alignment status, delegator count, last vote and how many polls and executives they have supported. The governance layer for MakerDAO/Sky wallets, governance dashboards, delegates and analytics. Live from vote.makerdao.com.

Sky (MakerDAO) Savings Rate & Protocol API

Live protocol stats from Sky, the decentralized stablecoin protocol formerly known as MakerDAO and the issuer of the USDS and DAI stablecoins — no key, nothing stored. This is the Sky-protocol view: the Sky Savings Rate (SSR) and DAI Savings Rate (DSR), the value locked in savings, the SKY staking yield and the overall ecosystem size, distinct from the generic DeFi-TVL, yields and lending APIs in the catalogue. The overview endpoint returns the latest ecosystem snapshot — the Sky Savings Rate APY, the savings TVL, the SKY staking APY, the farm APY, the total reward TVL, the whole-ecosystem TVL, the wallet count and the number of savings depositors. The savings endpoint returns the current savings rates: the live SSR and DSR and the dollar value deposited in each. The history endpoint returns the savings-rate timeline — per-day SSR, DSR and deposited totals — so you can chart how the on-chain risk-free rate has moved. Build DeFi yield dashboards, stablecoin-savings widgets, rate-comparison tools and treasury bots on top of the dominant decentralized stablecoin protocol. SSR and DSR are the on-chain savings benchmarks for USDS and DAI; rates are returned as percentages.

Nolus Chain API

Real-time on-chain data for Nolus (chain-id pirin-1), a Cosmos-SDK Layer-1 running a DeFi-lease / money-market protocol, secured by delegated proof-of-stake with NLS as its native coin. 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 NLS, commission rate and jailed flag — sorted by stake, plus the total bonded and not-bonded NLS. The supply endpoint returns the total NLS supply (in NLS and base unls), 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 Nolus 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 lease positions or token prices use a dedicated protocol/market API.

Nibiru Chain API

Real-time on-chain data for Nibiru (chain-id cataclysm-1), a Cosmos-SDK Layer-1 for DeFi with a native EVM, secured by delegated proof-of-stake with NIBI as its native coin. 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 NIBI, commission rate and jailed flag — sorted by stake, plus the total bonded and not-bonded NIBI. The supply endpoint returns the total NIBI supply (in NIBI and base unibi), 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 Nibiru 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 token prices or smart-contract reads use a dedicated market/contract API.
