## 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-98b4a9cd
```

Example prompt: Can you pull up all the token approvals for wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum — I want to see which contracts have spending permissions and if there are any unlimited approvals I should worry about?

## When to prefer this

Use this endpoint when you need to audit token spending allowances for a specific wallet on a supported EVM-compatible chain, particularly for security reviews, DeFi risk assessment, or pre-transaction safety checks. Prefer this over generic blockchain explorers when you need structured, machine-readable approval data with AI-powered risk context.

## Known failure modes

- Invalid or malformed wallet address returns error
- Unsupported chain identifier returns 400 or empty result
- Wallet with no approvals returns empty approvals array
- Network timeout or upstream data provider outage
- Payment failure via x402 protocol returns 402 status
