We are trying to achieve staking automation to nominationPool.

Is there any solution to get the number of bonded & unbound (unlocked) funds using the Polakdot-JS API?

We would like to fetch the amount(number) of funds in the nomination pool so that we could withdraw them automatically.

Thank you, The Starfish team

To get the basic info of the storage of the pool

const bondedPools = await api.query.nominationPools.bondedPools(pool_id);
console.log(`----- Storage for bonded pools: ${bondedPools} -----`);

And to get the rewards accumulated for the pool (When a members payout is claimed, the balance comes out for here):

const rewardPools = await api.query.nominationPools.rewardPools(pool_id);
console.log(`-----  Reward pools: ${rewardPools} -----`);

To get the information for a certain pool member (With their Account ID):

const poolMemberInfo = await api.query.nominationPools.poolMembers("13KTxXt8FnzoraYSkQNddrmb6sTvEY2VKyg8J9c1jRGPzF5D");
console.log(`-----  Member Info: ${poolMemberInfo} -----`);

Then if you want to automate the process to join a pool, nominate, bond tokens.... check the docs about how to call a Extrinsic with PolkadotJS: https://polkadot.js.org/docs/substrate/extrinsics/#nominationpools
