Get unconfirmed balance given an address

Question

Is there an API to get unconfirmed balance or txs, given a wallet address?

Thanks for opening this issue! A maintainer will review this in the next few days and explicitly select labels so you know what's going on.

If no reviewer appears after a week, a reminder will be sent out.

Think not. It would be possible to add this, as unconfirmed balance, but it is not a network wide thing, for example like there is no assurance for the unconfirmed balances to be the same, as transaction pools differ across the network and unconfirmed balance is the transaction pool balance of the wallet.

It would make sense, if you had your own node/pool to talk to.

The unconfirmed balance can be retrieved relatively easily using the current API. For example, to retrieve total received, unconfirmed (pagination not handled):

curl -H "API-Version: 2" -d recipientId=AbbN4RiMezriNuQUuts87KSks4nVChdjvW https://ark.exodus-prod.io/api/transactions/search \
  |node -e 'console.log(JSON.parse(fs.readFileSync(0)).data.reduce((sum, tx) => tx.confirmations === 0 ? sum + Number(tx.amount) : sum, 0));'

and similarly to retrieve total sent (replacing recipientId with senderId in the above). Then subtracting the two numbers would give the unconfirmed balance (assuming no transactions get confirmed in the meantime and no new ones arrive).

I do not think it is justified to add such a functionality in the API, given that it can be coded easily at the application level.
