How this service works
New trading pools created on Ethereum in the last N minutes on Uniswap v4, Uniswap v3: both tokens with symbol, name and decimals, fee tier, v4 hooks, whether it pairs with ETH, WETH or USDC, and quote liquidity where readable. Unvetted: many new pools are spam.
Output
A JSON object with the chain identifier ('eth'), pool count, a notes field warning about spam, and an array of pool objects each containing: transaction hash, DEX name (uniswap-v3 or uniswap-v4), block number, optional hooks address (v4 only), pool ID, token0 and token1 objects (name, symbol, address, decimals), approximate creation timestamp, fee tier in basis points, pairedWith (ETH/WETH/USDC or null), and quoteLiquidity (WETH or USDC amount held by v3 pool, null for v4 or unreadable).
Example use cases
New token launch scouting
“What are the newest Uniswap pools created on Ethereum in the last 30 minutes? Give me up to 20, and flag which ones are paired with ETH or USDC so I can identify new token launches.”
Uniswap v4 hooks monitoring
“Show me all new Uniswap v4 pools on Ethereum from the last 2 hours that have a hooks contract attached — I want to track which custom hook contracts are being used in newly deployed pools.”
High fee-tier pool detection
“List the 10 newest Ethereum Uniswap pools from the past 45 minutes and include the fee tier in basis points — I'm looking for pools with unusually high fee tiers like 9000 bps that might be worth investigating.”
Technical details
Endpoint
GEThttps://onchaincheck.dev/eth/new-pools?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time discovery of brand-new Uniswap v3/v4 pool deployments on Ethereum mainnet, especially when you need token metadata (symbol, name, decimals), v4 hooks addresses, or pairing information in a single call. Prefer this over general blockchain explorers when you want a structured, parsed feed of new pools without writing your own event-log queries. Note that results are unvetted and many pools are spam — use alongside a rug-check endpoint for due diligence.
Side effects
- Invalid 'minutes' value outside 5–240 range returns an error or empty result
- Invalid 'limit' value outside 1–50 range rejected by schema pattern
- No new pools in the lookback window returns count:0 and empty pools array
- Blockchain RPC latency may cause slight delays in very recent pool data
- Many returned pools are spam or scam tokens with no real liquidity — quoteLiquidity will be null or near-zero
- Payment failure (402) if USDC payment of $0.01 is not provided via x402 protocol
