Uniswap Protocol API

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.

Blockchair Multi-Chain Stats API

Live on-chain network statistics, mempool conditions and market data across the major UTXO blockchains and Ethereum, sourced from Blockchair. For any supported chain read the full network state — best block height, total and 24-hour block and transaction counts, mining difficulty, hashrate, coin circulation, on-chain transfer volume and chain size — or zoom into the mempool to see pending transactions, mempool size, transactions-per-second, the suggested fee per byte (or median gas price on Ethereum) and average and median transaction fees in native units and USD, or pull market data with the coin price in USD and BTC, 24-hour change, market capitalisation and dominance. Ten chains are covered: Bitcoin, Bitcoin Cash, Litecoin, Dogecoin, Dash, Zcash, Bitcoin SV, eCash, Groestlcoin and Ethereum. Distinct from single-chain mempool and gas feeds: this is one consistent multi-chain stats surface.

DexPaprika On-Chain DEX API

Live on-chain decentralized-exchange market data across 35+ blockchains, with no key. List every supported network with its 24h DEX volume, transaction count and pool count; read the DEXes active on any chain; pull the top liquidity pools ranked by volume; get full token detail with multi-window price stats; search across every chain for tokens, pools and DEXes; and read global coverage totals. The on-chain / DEX / liquidity-pool layer for DeFi dashboards, token analytics, trading and research — distinct from centralized-exchange ticker readers. Live from DexPaprika (by the CoinPaprika team); short cache only.
