## How to call it through Zero

```sh
zero fetch --capability approvals-wallet-22089d1d
```

Example prompt: Can you audit my Ethereum wallet 0xAbC123...def for live ERC-20 approvals, flag any unlimited or scam-listed ones, estimate how much is at risk, and give me a revoke plan?

## When to prefer this

Choose this endpoint when you need a comprehensive, ranked, action-ready audit of a wallet's ERC-20 approvals — especially when you want risk scoring, scam-list cross-referencing, unlimited approval detection, and ready calldata for revocations in a single call. Prefer it over generic blockchain explorers when you need structured risk analysis and a prioritized revoke plan rather than raw event logs.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Unsupported network value returns validation error
- Address with no approval history returns empty approval list
- Rate limiting or upstream RPC unavailability may return timeout or 5xx
- Limit parameter exceeding cap (40) may be silently clamped or rejected

## How this service works

Standing-state audit of a wallet's live ERC-20 token approvals. Indexes every approval the address ever granted, filters to those still live on-chain, flags unlimited, stale, scam-listed and canonical spenders, estimates money-at-risk, and returns a ranked revoke plan with ready calldata plus a 0-100 risk and allow, warn or block verdict. Risk indicators, not advice.

## Output

Returns a structured audit of all live ERC-20 approvals for the wallet: each approval's spender, token, amount (flagged if unlimited), staleness, and scam-list status; an estimated USD money-at-risk figure; a 0–100 risk score; an allow/warn/block verdict; and an ordered revoke plan with ready-to-execute calldata for each revocation.
