## 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-account-balance-spl-token-reader-fe6f8067 -d '<json body>'
```

Example prompt: What's the SOL balance and full list of SPL tokens held by the Solana wallet address 7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU?

## When to prefer this

Choose this endpoint when you need a single call to retrieve both native SOL balance and the complete SPL token portfolio for a Solana mainnet address. It is ideal for wallet auditing, portfolio tracking, airdrop verification, and DeFi agent workflows where you need a unified view of all holdings. Prefer this over rolling your own RPC calls when you need structured, pay-per-use access without managing Solana node infrastructure.

## Known failure modes

- Invalid base58 address format — address fails the regex pattern, returns error
- Account not found or unfunded — ok:true but funded:false with empty SPL token list
- Network timeout or RPC node unavailability — service returns error
- Payment failure — x402 payment not processed, request rejected before execution
- Malformed request body — missing params.address field causes validation error

## How this service works

Solana account read — SOL balance plus every SPL token the owner holds — Genesis402 / UnyKorn Operator Network

## Output

Returns a JSON object with: funded flag, SOL balance as a decimal string, raw lamport count, network identifier (solana:mainnet), an array of SPL tokens each including mint address, human-readable balance, decimals, and raw amount, plus a payment receipt with transaction hash, amount paid, and receipt ID.
