How this service works
558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.
Output
Returns a JSON object with the DEX name (Uniswap v3), network (base), and an array of pools matching the token pair. Each pool entry includes: pool contract address, current tick, token0/token1 symbols, fee percentage, token reserves (amounts of each token), active liquidity as a raw integer string, and the spot price of token_a denominated in token_b.
Example use cases
Real-time ETH price on Base
“What is the current WETH price in USDC right now on Uniswap v3 Base? I want the spot price from the 0.05% fee tier pool.”
Arbitrage pool comparison
“Pull the pool state for WETH and USDC across all fee tiers on Uniswap v3 Base — I need the spot price, reserves, and liquidity for each tier to spot arbitrage opportunities.”
DeFi liquidity monitoring
“Check the current token reserves and active liquidity in the USDC/DAI pool on Uniswap v3 Base so I can see how deep the market is before placing a large swap.”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/uniswap-pool?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time Uniswap v3 pool data specifically on the Base chain, including spot price, liquidity, reserves, and tick for a token pair. Prefer this over generic price APIs when you need on-chain pool mechanics (tick, active liquidity, pool address) rather than just a price quote, or when building DeFi strategies, arbitrage bots, or liquidity monitoring tools on Base.
Side effects
- Token symbol not recognized — use supported symbols (WETH, ETH, USDC, USDT, DAI, cbBTC) or a valid Base contract address
- No pool found for the requested fee tier — omit fee_pct to return all available tiers
- Invalid token address format causing a lookup failure
- Pool exists but has zero liquidity — returns pool address with zero reserves
- Network or RPC latency may cause stale or failed state reads
