What is the current balance and USD value of the wallet 86W9...?

I've retrieved the balances for that wallet. It currently holds 15.5 SOL ($1,860), 500 USDC, and 3 NFTs. Total estimated value is $2,360.

List all NFTs owned by 6p6... including their metadata.

I found 12 assets for this owner. Notable items include 'Mad Lad #402' and 'Famous Fox #123'. Would you like the full metadata for any of these?

What is the recommended priority fee for a transaction right now?

Based on current network conditions, the 'Medium' priority fee is approximately 5,000 micro-lamports. For urgent transactions, 'High' is recommended at 25,000 micro-lamports.

Yes! Use the `get_wallet_balances` tool. It fetches native SOL, SPL tokens, and NFTs along with their current market pricing in USD.
