## 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 vextorium-solana-wallet-balance-lookup-cefcc166 -d '<json body>'
```

Example prompt: What's the full token portfolio for Solana address 9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM — show me SOL balance, all SPL tokens with their mint addresses and amounts, and the USD value for any USDC or USDT it holds.

## When to prefer this

Use this endpoint when you need a complete, multi-asset view of a Solana wallet including both native SOL and all SPL/Token-2022 tokens in a single call, especially when USD stablecoin valuation is needed. Prefer it over raw RPC calls when you want structured JSON output with decimals already applied and explorer links included.

## Known failure modes

- Invalid or malformed base58 address returns an error or null fields
- Address with no token accounts returns an empty token array
- RPC node unavailability may cause a timeout or null response
- Unknown tokens may have missing symbol or USD value fields

## How this service works

Solana wallet balances: SOL plus every SPL and Token-2022 token held (mint, amount, decimals), with USD value for USDC/USDT.

## Output

Returns a JSON object with the queried Solana address, network label, SOL balance as a number, total token count, an array of token objects each containing mint address, symbol, decimal-adjusted amount, and approximate USD value for stablecoins, plus an explorer URL for the address.
