Uniswap Protocol API

healthy 4,535 Subscribers

Live protocol metrics for Uniswap, the largest decentralized exchange (DEX), keyless. Get the total value locked across every chain Uniswap is deployed on, DEX trading volume (24h / 7d / 30d / all-time, with change), protocol fees, and the top Uniswap liquidity pools with their TVL and APY (Uniswap v2 / v3 / v4). One combined overview endpoint snapshots it all. Live, nothing stored. The Uniswap-metrics layer for DeFi dashboards, analytics, yield and trading apps — distinct from generic DeFi/TVL browsers, this is Uniswap specifically, multi-chain.

DEX Pairs API

Live decentralised-exchange trading-pair data — no key, nothing cached. For any token or trading pair across every major chain and DEX (Ethereum, Solana, BSC, Base, Arbitrum, Polygon and dozens more, on Uniswap, Raydium, PancakeSwap and the rest) it returns the live on-DEX market: the price in USD and in the native quote token, the pool liquidity, the 24-hour volume, the fully-diluted valuation and market cap, the price change over 5 minutes, 1, 6 and 24 hours, and the count of buy and sell transactions. The search endpoint finds every pair matching a token symbol, name or address. The token endpoint returns all the pools a token trades in, ranked by liquidity, so you can find where the real liquidity is — Wrapped Ether trades in pools led by a Uniswap WETH/USDC pool with tens of millions in liquidity. The pair endpoint returns one specific pool by chain and pair address in full detail. This is the DEX market-data layer every trading, screener, wallet, sniping and portfolio app needs — real pools, real prices, every chain. Live from DexScreener, nothing stored. Distinct from aggregate DEX-volume and centralised-exchange ticker APIs — this is per-pair on-DEX data. 4 endpoints.

Unichain API

Live Unichain on-chain data via Blockscout. Unichain is Uniswap's Ethereum L2; gas and balances are in ETH. Network stats, gas prices, latest blocks, a block by height or hash, address detail with ETH balance, a transaction by hash, ERC-20 token metadata and a universal search across addresses, tokens, blocks and transactions. Real data, no key.

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

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.
