Aave Protocol API

healthy 3,951 Subscribers

Live protocol metrics for Aave, the largest decentralized lending protocol, keyless. Get the total value locked across every chain Aave is deployed on, the per-asset lending markets with their supply APY (base + rewards), 30-day average and TVL across Aave v3 / v4, and protocol fees. One combined overview endpoint snapshots it all. Live, nothing stored. The Aave-metrics layer for DeFi dashboards, yield, lending and risk apps — distinct from DEX and generic DeFi/TVL browsers, this is Aave lending markets specifically, multi-chain.

DeFi Lending Rates API — oanor API marketplace

DeFi Lending Rates API

The supply and borrow rates of on-chain money markets, compared across every major DeFi lending protocol and chain at once — live from DeFiLlama, no key. The same asset earns and costs a different rate on every protocol and every chain: USDC might pay 3% to supply on Aave v3 Ethereum and cost a fraction to borrow somewhere else, and those rates move every block. A single protocol's reserves are only part of the picture; what a lender or borrower wants is the cross-protocol, cross-chain comparison. This API joins DeFiLlama's pool yields with its lend/borrow dataset into one money-market table: for every lending reserve it gives the supply APY (base + reward), the borrow APY (base + reward), the utilisation, the loan-to-value and the dollar size of the supplied and borrowed pools. The markets endpoint returns the full table (filter by asset, chain, protocol, stablecoin, minimum size); the best endpoint returns the top venues to supply an asset (highest APY) or to borrow it (lowest APY) right now; the asset endpoint summarises one asset across all its markets — the min, max, average and median supply and borrow APY, plus the single best place to lend and to borrow. Ranking surfaces exclude DeFiLlama-flagged outlier pools and impossible (>100%) utilisation, so the best rate is a real, harvestable one. The cross-protocol money-market-rates cut — distinct from TVL analytics (which size protocols, not their rates), single-protocol lending APIs (one venue each), and perpetual funding-rate APIs (a different rate entirely).

Superposition API — oanor API marketplace

Superposition API

Live EVM on-chain data for Superposition (chain id 55244) — an Arbitrum-Orbit DeFi Layer-3 with ETH gas and on-chain yield-bearing Super Assets — served directly from the public Superposition JSON-RPC with server-side resilience. The status endpoint returns the chain and network id, the latest block height and the node client version. The block endpoint returns a block by number (or the latest) with its hash, parent hash, timestamp, transaction count, gas used and gas limit, miner and size. The gas endpoint returns the current gas price in both wei and gwei. The balance endpoint returns the ETH balance and outgoing transaction count for any address, converted from base wei (18 decimals) into whole ETH with exact big-integer scaling. Every figure is read live from the chain over JSON-RPC — nothing bundled or modelled — behind a short server-side cache with keep-warm so the feed stays fast and fresh. Ideal for explorers, wallet and dashboard tooling, gas trackers, address monitors and DeFi analytics across the Superposition and Arbitrum-Orbit ecosystem. Live keyless upstream. 5 endpoints.

Nolus Chain API — oanor API marketplace

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 — oanor API marketplace

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.
