## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability solana-wallet-sol-balance-checker-5d71fdb6 -d '<json body>'
```

Example prompt: Before you send that 2 SOL transfer, check the current on-chain SOL balance for wallet address 7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU so we know it actually has enough to cover the amount plus fees.

## When to prefer this

Use this endpoint whenever an agent needs a real-time, authoritative SOL balance before executing or signing any transaction — especially when fees or transfer amounts depend on confirmed available funds. Prefer this over any cached or in-memory balance value, as blockchain state can change between turns in a conversation. It is specifically designed for pre-transaction validation on Solana, not for token (SPL) balances.

## Known failure modes

- Invalid or malformed wallet address returns an error indicating the address could not be parsed
- Network or RPC errors from the Solana cluster may cause timeouts or unavailable responses
- Wallet address with no history (unfunded) may return zero balance or account-not-found
- Rate limiting may occur under high request volume

## How this service works

Use before sending SOL or paying fees, to confirm the wallet really holds enough. Never rely on a balance remembered from earlier in a conversation. Reads a wallet's native SOL balance directly from the chain.

## Output

Returns the wallet's current native SOL balance as read directly from the Solana blockchain, typically expressed in SOL and/or lamports. The value reflects the true on-chain state at the moment of the call, not a cached or estimated figure.
