How this service works
Pay-per-call data for AI agents, paid in USDC on Base with x402: token risk checks (rug check) on Base, Ethereum, Arbitrum, Optimism, Polygon and Solana, onchain reads (balances, transactions, gas, contracts, NFTs, whale trades, new pools, ENS and Basenames), ECB exchange rates, and Canadian sales tax and business days.
Output
A list of newly created Uniswap v3/v4 pools on Ethereum mainnet, each containing both tokens' symbol, name, and decimals; the pool fee tier; Uniswap version; any v4 hook addresses; a flag indicating if the pool pairs with ETH, WETH, or USDC; and quote liquidity where available. Results are ordered newest first, up to the requested limit. Many pools may be spam or low-quality.
Example use cases
New token launch scouting
“What are the 25 most recently created Uniswap pools on Ethereum from the last 2 hours? I want to see both token names and symbols, the fee tier, and whether they pair with ETH, WETH, or USDC.”
Uniswap v4 hooks discovery
“Show me new Ethereum Uniswap v4 pools created in the last 60 minutes — I'm specifically interested in which ones have v4 hooks attached and what their fee tiers are.”
DeFi liquidity monitoring alert
“List the 10 newest Ethereum Uniswap pools from the last 30 minutes that pair with USDC, including liquidity amounts and token details, so I can flag any high-liquidity launches.”
Technical details
Endpoint
GEThttps://ca-tax-api-mainnet.lxtap.workers.dev/eth/new-pools?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time discovery of newly launched Uniswap v3 or v4 liquidity pools specifically on Ethereum mainnet, with rich token metadata and pairing context. Prefer it over generic block explorers when you need structured, agent-ready pool data including fee tiers, v4 hooks, and ETH/USDC pairing flags without parsing raw logs. Choose the Arbitrum sibling endpoint for Arbitrum One pool discovery instead.
Side effects
- Invalid 'minutes' value outside 5–240 range returns an error or capped result
- Invalid 'limit' value outside 1–50 returns an error
- No pools found in the time window returns an empty list
- On-chain RPC issues may cause timeouts or partial data
- Spam/scam pools included in results with no automatic filtering
- Token metadata may be missing or unreliable for very new tokens
