## 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-approvals-lookup-5a93529a
```

Example prompt: Can you pull up all the token approvals for wallet address 0xABCDef1234567890abcdef1234567890abcdef12 on Ethereum and flag any unlimited approval amounts that could be risky?

## When to prefer this

Use this endpoint when you need to audit ERC-20/token spending approvals for a specific wallet address on a particular blockchain. Ideal for security audits, pre-revocation reviews, DeFi risk assessments, and smart contract permission analysis. Prefer this over generic block explorers when you need structured, machine-readable approval data that an agent can parse and act on programmatically.

## Known failure modes

- Invalid chain identifier returns an error or empty result
- Malformed or invalid wallet address returns a 400-level error
- Unsupported chain not indexed by LensCrypt returns no data
- Payment failure via x402 protocol results in 402 Payment Required
- Rate limiting or quota exhaustion returns an error response
- Newly created wallets with no approvals return empty approval list
