How this service works

New trading pools created on Base in the last N minutes on Uniswap v4, Uniswap v3 or Aerodrome: 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

Returns a JSON object with the chain name, pool count, and an array of pool objects. Each pool includes the transaction hash, DEX name (uniswap-v3, uniswap-v4, aerodrome), block number, approximate creation time, pool ID, hooks address (v4 only), fee tier in basis points, paired asset (ETH/WETH/USDC or null), quote liquidity (WETH or USDC amount held, null for v4 or unreadable), and full token0/token1 metadata (name, symbol, address, decimals). Includes a notes field warning that many new pools are spam or scams.

Example use cases

Spotting new token launches on Base

“What new liquidity pools have been created on Base in the last 30 minutes? Show me up to 20, with the token names and symbols so I can see what just launched.”

Monitoring Uniswap v4 hook deployments

“Pull the newest pools on Base from the last 2 hours — I specifically want to see any Uniswap v4 pools that have hooks attached and what address those hooks are.”

Scouting ETH-paired pools for trading signals

“List the 25 most recent Base trading pools from the last hour and tell me which ones pair with ETH or WETH, including the fee tier and any available liquidity figures.”

Technical details

Endpoint

GEThttps://onchaincheck.dev/base/new-pools?utm_source=zero.xyz

When to prefer

Use this endpoint when you need real-time discovery of newly created liquidity pools on the Base blockchain across Uniswap v3, Uniswap v4, and Aerodrome. It's the right choice when you want to monitor new token launches, detect fresh trading pairs, or scan for pools with specific characteristics like ETH pairing or v4 hooks. Prefer this over generic block explorers when you need structured, pre-parsed pool metadata including both token details, fee tiers, and liquidity in a single call.

Side effects

Invalid minutes value outside 5-240 range returns an error
Invalid limit value outside 1-50 range returns an error
RPC or indexing lag may cause stale or incomplete pool data
Very new pools may have incomplete token metadata if contracts are non-standard
Uniswap v4 quoteLiquidity is always null due to shared PoolManager architecture
Payment failure or missing x402 payment header returns 402 Payment Required
