## 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 evm-wallet-approval-risk-auditor-21f91194 -d '<json body>'
```

Example prompt: Can you audit my Ethereum wallet 0xAbC...123 for risky token approvals — check all ERC20, ERC721, and ERC1155 approvals against current on-chain state, flag any dangerous spenders, and give me the unsigned calldata to revoke the risky ones?

## When to prefer this

Use this endpoint when you need to perform a security audit of an EVM wallet's token approval surface area, especially when you need live on-chain state verification rather than cached data, and when you need actionable unsigned revoke calldata ready for signing — not just a report. Prefer this over generic blockchain explorers when you need programmatic, machine-readable risk signals and revocation transactions in a single call.

## Known failure modes

- Invalid or malformed wallet address returns a validation error
- Unsupported chain ID results in an error indicating the network is not supported
- RPC node unavailability causes a timeout or upstream connectivity error
- Wallet with no approvals returns an empty approval list
- Rate limiting or payment failure returns a 402 or 429 status

## How this service works

Audit EVM wallet ERC20, ERC721, and ERC1155 approvals, flag risky spenders, and return unsigned revoke calldata after current-state checks.

## Output

Returns a list of current token approvals categorized by risk level, identifies flagged risky spender addresses, provides the current on-chain state of each approval, and includes unsigned revoke calldata that can be signed and broadcast to remove dangerous permissions.
