## 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-by-chain-and-address-f3c0d2d1
```

Example prompt: Can you pull up all the token approvals for my wallet 0xABC...123 on Ethereum so I can see which contracts have spending permissions?

## When to prefer this

Use this endpoint when you need to audit or inspect token spending approvals (allowances) for a specific wallet address on a given blockchain. Ideal for security audits, DeFi risk assessments, or helping users identify and revoke potentially dangerous unlimited approvals.

## Known failure modes

- Invalid or malformed wallet address returns error
- Unsupported chain identifier returns error or empty result
- Wallet with no approvals returns empty list
- Payment not completed via x402 returns 402 Payment Required
- Network timeout or upstream data unavailability returns 5xx error
