How this service works
Resolves a pool either by address or by chain, token pair and DEX, then reads token0, token1, fee tier, reserves, in-range liquidity and the current tick straight from the contract. Exit impact is not estimated from a formula but simulated: for Uniswap V3 through the official Quoter contract via eth_call, which walks the same ticks a real swap would and reports how many it crossed; for constant-product and Solidly pools through the pool maths or the pool own getAmountOut. Nothing is ever execute
Output
Returns token0 and token1 addresses, fee tier, pool reserves, amount of in-range liquidity, and the current tick read directly from the contract. For Uniswap V3, exit impact is simulated via the official Quoter contract (eth_call) reporting ticks crossed; for constant-product and Solidly pools, exit impact uses pool math or getAmountOut. No transaction is ever submitted.
Example use cases
Check Uniswap V3 pool depth before trading
“What's the current in-range liquidity and tick for the WETH/USDC Uniswap V3 pool on Ethereum using the 3000 ppm fee tier? I want to see how deep it is before placing a large order.”
Compare pool reserves by token pair and DEX
“Can you look up the reserves and liquidity for the USDC/DAI pool on Curve on Arbitrum? I need the raw on-chain numbers, not an estimate.”
Simulate exit impact for a large DeFi position
“I'm about to exit a big position in the WBTC/ETH Uniswap V3 pool at 0x1234...abcd on Polygon — can you simulate how many ticks the swap would cross and what the exit impact looks like?”

Endpoint
POSThttps://defi.halowerk.com/pool/liquidityWhen to prefer
Choose this endpoint when you need raw, on-chain liquidity data (reserves, tick, in-range liquidity) for a specific pool and want exit impact simulated — not estimated from a formula — via the same code path a real swap would use. Prefer it over generic price APIs when you need tick-level granularity for Uniswap V3 or accurate constant-product math for Solidly pools, and when you need to avoid any on-chain execution side effects.
Side effects
- Pool address not found or invalid (0x address malformed)
- Token pair + DEX combination does not resolve to a known pool
- Chain not supported (only base, ethereum, arbitrum, optimism, polygon)
- Fee tier provided does not match any existing pool tier
- RPC or contract call failure for the given chain
- Pool exists but has zero liquidity, returning empty reserves
- Invalid DEX id provided with token pair
