# Get Pools by Token Addresses

Pump AMM, the native decentralized exchange for Pump.fun tokens, utilizes liquidity pools to facilitate trading. Each pool is defined by a liquidity pair of token mint addresses. This pair is denoted by <mark style="color:yellow;">baseMint</mark> and <mark style="color:yellow;">quoteMint</mark> addresses on Pumpswap. We can add filters to these two fields, to retrieve specific pool details involving a particular liquidity pair.\
For instance we are trying to get liquidity pools involving USDC and SOL, so we filter `baseMint`and `quoteMint`fields using the *\_in* filter.

You can directly copy paste this code on <mark style="color:yellow;">replit</mark> and see it in action.

We can also query liquidity pool involving a particular <mark style="color:yellow;">token address</mark>, for that we would have to filter the `baseMint` or `quoteMint` field using the *\_in* filter.
