## 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 wallet-drainer-protection-token-approval-risk-scanner-35398de6
```

Example prompt: Scan my wallet 0xABC123...def for all live token approvals across major EVM chains and tell me which ones are risky or need to be revoked — flag any malicious contracts, unlimited allowances, or unverified spenders.

## When to prefer this

Use this endpoint when an AI agent or user needs a comprehensive, deterministic security audit of all outstanding token approvals across EVM chains — especially when assessing wallet drainer exposure, preparing for revocation, or doing pre-transaction security checks. Prefer this over general on-chain data tools because it provides opinionated risk ranking and an actionable revocation list rather than raw approval data.

## Known failure modes

- Invalid or malformed wallet address returns 400 error
- Unsupported EVM chain returns scope error
- RPC node timeout for one or more chains results in partial scan with warning
- No approvals found returns empty list (not an error)
- Payment not received results in 402 response

## How this service works

Wallet drainer-protection scan: enumerates every live token approval (ERC-20, ERC-721, ERC-1155) your wallet has granted across major EVM chains, risk-ranks each spender (malicious flags, unverified contracts, unlimited allowances, EOA spenders), and returns a prioritized revocation action list. Deterministic security scan.

## Output

A structured list of all active token approvals (ERC-20, ERC-721, ERC-1155) granted by the wallet, each annotated with a risk rank, malicious flags, contract verification status, allowance amount (unlimited vs bounded), spender type (EOA vs contract), and a prioritized revocation action list ordered by severity.
