# DEX Aggregators API > Live trading volume routed through DeFi DEX aggregators — Jupiter, 1inch, CowSwap, Paraswap, OKX Swap, KyberSwap and more — powered by the public DeFiLlama aggregators feed, no key, nothing stored. Aggregators don't hold liquidity themselves: they split each trade across many underlying decentralized exchanges to get the best price, so their volume is the single best measure of where real swap flow actually routes. The overview endpoint returns total aggregator volume over the last 24 hours, 7 days and 30 days plus every aggregator ranked by what it routes, with its category and the chains it covers. The aggregator endpoint returns a single aggregator's volume across 24h / 7d / 30d / all-time. The chain endpoint returns aggregator volume and the top routers for one blockchain (Solana, Ethereum, Base). See which router dominates each chain and how swap flow shifts. This is the swap-routing / aggregator-volume cut of DeFi — distinct from the spot-DEX-volume, fees-and-revenue, TVL and exchange-ticker APIs in the catalogue. ## Authentication All requests require your oanor API key in the `x-oanor-key` header.
