## 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 nexusapi-crypto-address-token-lookup-fe8759e7 -d '<json body>'
```

Example prompt: Can you look up all the tokens held by the wallet address 0x1234abcd...5678 and tell me what it holds?

## When to prefer this

Use this endpoint when you need a quick, pay-per-call token balance lookup for a blockchain wallet address without managing API keys. Ideal for agents that need on-demand crypto portfolio data and are already integrated with x402 USDC micropayments on Base.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Address with no token holdings returns an empty list
- Unsupported chain or network may return no results
- Rate limiting or payment failure (HTTP 402) if USDC payment is insufficient
- Network timeout if the underlying blockchain data provider is slow

## How this service works
