## 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-mint-instant-intel-sol-balance-lookup-f7f7fa23
```

Example prompt: What's the current SOL balance for the Solana wallet address 9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM? Give me both the lamports and the SOL amount.

## When to prefer this

Use this endpoint when you need a fast, low-cost, confirmed SOL balance for any Solana address without managing your own RPC node or API keys. The 2-second cache makes it ideal for near-real-time balance checks in agent workflows, pre-transaction validation, and portfolio monitoring. Prefer it over raw RPC calls when you want a simple HTTP GET with no authentication overhead and a clean JSON response.

## Known failure modes

- Invalid or malformed base58 address returns an error response
- Address not found on-chain (never funded) may return 0 lamports or an error
- RPC node unavailability may cause a timeout or 5xx error
- Cache staleness up to 2 seconds may reflect slightly outdated balance in high-frequency scenarios

## How this service works

SOL balance of any Solana address (lamports + SOL string, confirmed, cached <=2 s).

## Output

Returns a JSON object containing the queried Solana address, its balance in lamports (integer), and its balance as a SOL string (e.g. '1.5'). Data is confirmed on-chain and served from a cache no older than 2 seconds.
