## 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 lenscrypt-token-approval-analytics-chain-address-lookup-77126511
```

Example prompt: Can you pull up all the token approvals for my Ethereum wallet 0xABC...123 and tell me which contracts have unlimited spending access?

## When to prefer this

Use this endpoint when you need to audit token spending approvals for a specific wallet address on a supported EVM-compatible chain. Ideal for security checks, pre-transaction risk reviews, or wallet hygiene audits. Choose this over generic blockchain explorers when you need structured, agent-consumable approval data without manually parsing chain data.

## Known failure modes

- Invalid or malformed wallet address returns an error response
- Unsupported chain identifier causes a lookup failure
- Rate limiting or payment failure via x402 protocol returns a 402 or 429 error
- Wallet with no approvals returns an empty list
- Network timeout from on-chain data provider
