# Get Pool by Token Addresses

Liquidity Pools are smart contract based vaults that are associated with specific <mark style="color:yellow;">liquidity token pairs</mark>. With SHYFT's GraphQL APIs, we can query Liquidity Pools based on the tokens associated with them for Meteora DLMM. The liquidity pairs are denoted by the following fields: `tokenXMint` and `tokenYMint`.

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