## How to call it through Zero

```sh
zero fetch --capability solana-wallet-balance-09a3c440
```

Example prompt: What's the current SOL and token balance for Solana wallet 9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM, and what's the total USD value?

## When to prefer this

Use this endpoint when you need to look up on-chain Solana wallet balances including both native SOL and any SPL or Token-2022 tokens, especially when USD valuation is needed. Prefer it over EVM gas or balance endpoints when the wallet is on the Solana blockchain specifically. Ideal for confirming payments, auditing holdings, or enriching user profiles with Solana portfolio data.

## Known failure modes

- Invalid or malformed Solana wallet address returns an error
- Wallet with no tokens returns empty balances but no error
- Token prices unavailable for obscure SPL tokens — USD value omitted for those
- Rate limiting or upstream Solana RPC timeout causing a 5xx response
- Payment not confirmed if x402 micropayment fails

## How this service works

SOL and SPL token balances of a Solana wallet (Token and Token-2022), with USD values and total where a price is known. Use to check a Solana wallet or confirm a payment arrived.

## Output

Returns a structured list of all SOL and SPL token balances (including Token-2022 standard) held by the wallet, each with its token symbol, raw and formatted balance, and current USD value where a price feed is available, plus a total portfolio value in USD.
