Fetch and query a Pumpswap AMM pool info based on pool address.
Pump.fun has now launched its own decentralized exchange called PumpSwap, to which pump tokens migrate to after completing their bonding curve. Using Pump AMM's GraphQL API, we can query and filter pool data based on any available field. Here, we filter by the pubkey field to fetch pool details for the corresponding pool.
You can directly copy paste this code on replit and see it in action.

const result = await fetch(`https://programs.shyft.to/v0/graphql/accounts?api_key=${SHYFT_API_KEY}&network=mainnet-beta`, //SHYFT's GQL endpoint
{
method: "POST",
body: JSON.stringify({

variables: {},

const { errors, data } = await result.json();
console.dir(data, { depth: null });
}
getPoolDetailsByPoolAddress("DCQWy2Jx8vodKaznKdYWv5BXnXDgFgjHqFgKHypzr3x");
//pool address for which we are fetching data
The response contains base_mint and quote_mint which is the liquidity pool pair. The lp_mint field is the liquidity pool token address. Please note that more fields such as pool_base_token_account, pool_quote_token_account, lp_supplycan also be cherrypicked, or omitted as per your requirement.
