## 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 sleuth-ai-wallet-holdings-api-2691f417 -d '<json body>'
```

Example prompt: Can you pull up the current token holdings for wallet 0xAbCd...1234 on Base and show me what tokens it holds, their balances, and USD values?

## When to prefer this

Use this endpoint when you need a comprehensive, structured breakdown of all tokens held by a specific on-chain wallet address, including USD-denominated values and portfolio percentage shares. Prefer this over generic block explorers when you need machine-readable, agent-consumable output with natural language summaries for downstream reasoning. Best suited for on-chain investigation, portfolio analysis, counterparty due diligence, or whale-watching tasks on Base or compatible EVM chains.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Wallet address with no on-chain activity may return empty holdings
- Network timeouts or on-chain data unavailability may cause failures
- Insufficient USDC balance for x402 payment will block the call
- Unsupported blockchain network may return no data

## How this service works

Pay-per-call on-chain investigation API (x402, USDC on Base).

## Output

Returns a structured JSON response containing a list of token holdings for the queried wallet, including token identifiers, raw balances, USD values, and percentage share of the total portfolio. Also includes a natural language summary of the wallet's holdings and a unique request ID for tracing.
