## How to call it through Zero

```sh
zero fetch --capability nft-operator-approval-auditor-ec9f463b
```

Example prompt: Can you audit my wallet 0xAbc123...def on Ethereum for any live NFT operator approvals, flag any scam or stale ones, and give me a revoke plan with the calldata I need to remove the risky ones?

## When to prefer this

Use this endpoint when you need a comprehensive, on-chain-verified audit of a wallet's NFT operator approvals with actionable revoke calldata — not just a static list. Prefer it over generic block explorers when you need scam flagging, stale detection, risk scoring, and ready-to-submit transaction data in one call across Base, Ethereum, Arbitrum, Optimism, and Polygon.

## Known failure modes

- Invalid or non-checksummed wallet address returns a 400 error
- Unsupported network name returns validation error
- Rate limiting or upstream RPC node errors may cause 503 or timeout
- Wallet with no NFT approvals returns empty approval list with risk score 0
- limit exceeds cap of 40 and is silently clamped or rejected

## How this service works

Standing-state audit of a wallet's live NFT operator approvals. Indexes every ApprovalForAll the address granted, filters to operators still live on-chain via isApprovedForAll, flags scam-listed, stale and canonical operators, and returns a ranked revoke plan with ready setApprovalForAll calldata plus a 0-100 risk and allow, warn or block verdict. Risk indicators, not advice.

## Output

Returns a list of all live NFT operator approvals (ApprovalForAll) for the wallet, each labeled as scam, stale, or canonical, along with a 0-100 aggregate risk score, an allow/warn/block verdict, a ranked revoke plan ordered by priority, and ready-to-submit setApprovalForAll calldata for each operator to be revoked.
