## 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 1gateway-solana-wallet-balance-lookup-0a8147eb
```

Example prompt: What's the SOL balance and full list of SPL tokens held by the Solana wallet CV8t6fnSsckB3bzJSVRxQjVvTgdB35q11Fu3eaF1nz8u right now?

## When to prefer this

Use this endpoint when you need a complete, single-call snapshot of a Solana wallet's on-chain state — SOL plus all token balances — without wanting to parse raw RPC responses yourself. It is ideal for portfolio display, eligibility checks, or pre-transaction audits. It does not return prices, so pair it with a price feed if USD valuation is needed. Prefer it over raw Solana RPC calls when you want a normalized, structured response at a fixed $0.002/call cost.

## Known failure modes

- 400 Bad Request if the address is not a valid base58-encoded 32-byte public key (not charged)
- Empty token array if the wallet exists but holds no SPL tokens
- Slot lag if the RPC node is slightly behind mainnet tip
- Truncated flag set to true if the wallet holds more than 50 non-zero tokens (only first 50 returned)
- Address not found on-chain returns zero balances (not an error)

## How this service works

Use when an agent needs what a Solana address holds in one call. Input: address. Output: JSON slot, SOL balance, every non-zero token (mint, token account, program, decimals, raw and decimal balance, frozen flag; first 50), counts of token and empty accounts. Chain state only, no prices. Bad input: 400, not charged. Example: ?address=CV8t6fnSsckB3bzJSVRxQjVvTgdB35q11Fu3eaF1nz8u

## Output

A JSON object containing: the current Solana slot, the wallet's SOL balance in both decimal and raw lamports, an array of up to 50 non-zero SPL token entries each with mint address, associated token account, program, decimals, raw and decimal balance, and frozen status; plus counts of total token accounts, non-zero token accounts, empty token accounts, a truncated flag, and the RPC node that served the request.
