Uniswap on Base: DEX data API

Uniswap swaps on Base

Each row is one swap from the transactions endpoint: the pair, its value in USD at the time, and the Uniswap version it went through.

Your first Uniswap call

Find the busiest pools for one version, then read the swaps going through one of them. Token symbols come back in every transaction row, so there is no second lookup.
