## 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-token-holdings-lookup-bb363962 -d '<json body>'
```

Example prompt: What SOL and token balances does the Solana wallet HcjfmZLgWRZzwj4deEiS7pewc4KBYSw39mW5nTyt3pz2 currently hold, including any stablecoin USD values?

## When to prefer this

Choose this endpoint when you need a quick, structured snapshot of a Solana wallet's on-chain holdings including SOL balance and SPL token list, especially when stablecoin USD values are needed. It is purpose-built for Solana (base58 addresses) and returns a clean, agent-friendly schema. Prefer it over generic block explorers when you need machine-readable output with USD approximations for stablecoins, and over EVM-focused endpoints when the target address is on Solana.

## Known failure modes

- Invalid or malformed base58 address returns an error or empty result
- Address with zero token accounts returns empty tokens array
- Network congestion may cause stale or delayed on-chain data
- USD values only provided for recognized stablecoins (USDC, USDT); other tokens show null for value_usd_approx
- Payment failure (insufficient USDC) blocks the call under x402 protocol

## How this service works

558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.

## Output

A JSON object containing the wallet address, network ('solana'), SOL balance, total number of SPL tokens, an array of token objects (each with mint address, symbol, decimals, amount, and approximate USD value for stablecoins like USDC/USDT), and a Solscan explorer URL for the address.
